Proof coins if bought at the right price are quite a good way to protect yourself should the price of gold/silver drop. They tend to hold their value as they have lower mintages and are collectibles. But you have to sell them privately to get the premiums you would expect/want. Bullion gold is good for quick liquidation with a dealer.

Sovereign has a default nomination value of one pound sterling since inception. Sovereign produce by the Royal Mint is legal tender in United Kingdom, settlement is another matter of contention.

As expected, the RM is going to release a Piedfort Sovereign this year, with the same Royal Coat of Arms design as the Proof Sovereign.

A piedfort is not necessarily double the weight and thickness, it is essentially heavier, although this also implies it must be thicker.
For once Wikipedia has got it right:
A piedfort  French: pied-fort or piéfort is an unusually thick coin, often exactly twice the normal weight and thickness of other coins of the same diameter and pattern. Piedforts are not normally circulated, and are only struck for presentation purposes by mint officials (such as patterns), or for collectors, dignitaries and other VIPs. Piedfort is commonly misspelled as "piefort".

We ought to have a "Talent" competition, especially as a "talent" can also refer to a coin or weight.

Denominations stated on 'British' coins is an interesting one. I say British but actually mean English before 1707. Scottish coins etc. might have their own examples but I know nothing about those.
The first English coins I can think of with denominations stated are James I coins from the 1603-25 era. The silver/gold coins often have the denomination stated in Roman numerals - VI for sixpence, XX for the Pound coin (20 shillings, which went by many names), XXX for half crown (30 pence).
This continued through to the end of hammered in 1662.
Then stated denominations were mostly scrapped, except for Maundy coinage which stated the value in a variety of ways. Interlinked C's during Charles II's reign, Roman numerals (actually I for Iacobus) during James II's reign, giving way to Arabic numerals onwards from 1689.
The farthing joined the value stated club in 1799, the Sixpence and Shilling joined in 1831-4, although had a brief spell out of it again during 1887-1892. The Britannia groat hit the ground running in 1836 with denomination stated.
The florin debuted in 1849 with two denominations 'one florin' and 'one tenth of a pound' stated proudly.
The bronze coinage of 1860s onwards started with denominations.
Realistically there was a slow shift to full denominations stated from the 1830s onwards. Up until 1887, when there was a blip backwards to no denominations stated throughout the jubilee era (except denominations 6d downwards, which kept them).
By the old head era the denominations started up again. The crown upwards though didn't, as stated in other posters' replies.
So it's way more complex than at first glance.

The whole discussion regarding collecting, stacking and liquidity is interesting and there will be differing views.  I, too, am relatively new to the the world of physical PM, but have some thoughts:
1.  Silver coins are nice, but I question the real sense if truly stacking.  Are we really thinking that at some point we would use them in exchange for goods and services?  Is there a high risk that once you start buying coins, the greed monster kicks in and, where you may have deliberately said "split between Brits and Maples" only, it soon turns into Kooks, Krugers (ASEs if someone is selling cheaper than normal) etc? Also, they tarnish!
2.  One common maxim is that you watch the gold versus silver ratio.  Whilst the number is deemed high, as now at a little under 80:1, you buy silver.  When that number drops, perhaps to 50, you sell the silver and buy gold.  If you follow this, then why not just buy manageable bars (10oz, 250g to 1kg)?
3. Everyone considers different factors when discussing the future of silver. My hope is that any manipulation of the price is relaxed/stopped, but I am also conscious that something seismic may catch us all off guard as Govs could introduce measures to control the price in line with a growing industrial consumption (Indeed, something sooner may happen if the bank exposure is truly understood). If the former, and the aforementioned ratio rebalances, the stackers are quids in with multiple 100% ROI. If the latter, we could all be sitting with dead ducks and wishing we just bought gold.
4. Sovs v Brits.  Yes, Sovs theoretically are easier to sell on at a time of need.  If you are in a time of need, is £360 or £720 going to be sufficient?  
5. If saving for the future, ergo the long investment, then the common cry is the cost now and the premium is less important (than if you are flipping). If you are saving for the future, perhaps you are investing a set amount per month, then surely it's best still to buy the highest amount at the lowest premium?  The aesthetics and heart needs to take a second place to a more business approach.  Of course you can go down the more specific long term investment, buying a rare coin or sets of highly graded or similar, but that is another game and not stacking.
6. Consider the current CGT and VAT rules.
7. A couple of final thoughts: 
a) Collecting coins, gold or silver, can be addictive. Don't get attached
b) There are many sovereigns; there are many different Au and Ag coins. Limit your horizon
c) Consider storage space and insurance
d) Talk to people that have been in this market for sometime.  I have found people on TSF to be extraordinarily kind when sharing advice and thoughts as well as services
7. Last point is that I wager that what you are planning now, your strategy, will have changed within 12 months.
All the best with whatever you do.

Today's Daily Telegraph carries a news report on page 11, headed "Secretive collector has more coins than the Royal Mint"
While I was more than interested in hearing about this for the first time, I have already spotted three typical journalistic errors, and I have not yet finished the second paragraph.
Doing a Google search for "coins" under "news", shows only one relevant result, so kudos to the Telegraph for being the first in the UK to report it. Just a shame it can't get simple facts right, but that's about normal for most newspapers, and other media.
I very much doubt that he has more coins than the Royal Mint, which produces about a million pennies a day, besides many other denominations and coins for other countries. It therefore throws the Telegraph's claim into doubt. In fact it is plainly ridiculous.
It also says in a caption under a 1957 gold sovereign:
In 1957 gold sovereigns were issued for investment for the first time during Elizabeth II's reign, and were the only gold sovereigns produced for circulation between 1932 and the introduction of British decimalisation in 1971...
In one sentence, it contradicted itself, first saying they were issued for investment, then saying produced for circulation. It slao ignores the fact that sovereigns were issued and dated 1958, 1959, 1962, 1963, 1964, 1965, 1966, 1967, and 1968.
The online version says
"Billionaire ‘Tyrant’ unveils collection of coins minted by every English and British monarch
Secretive collector reveals identity after completing 17-year mission to assemble a hoard that surpasses even that held by the Royal Mint"
By Craig Simpson 12 March 2022 • 7:00am
A tech billionaire known as “the Tyrant” has finished the first coin collection spanning the entirety of English and British history, with an array of currency more complete than that of the Royal Mint.
Coins minted by every monarch – all the way back to 7th-century Anglo-Saxon kings – have been compiled by the secretive collector to form part of a £300 million set known as the “Tyrant Collection”.
The mysterious figure behind the set, until now known only as “the Tyrant” in the numismatic community, has been unmasked as a US tech billionaire who has spent the past 17 years assembling the most valuable coin hoard in the world.
Dan O’Dowd kept both his identity and his ambition to own a coin featuring every English and British monarch secret to avoid being held to ransom on the price, but the designer of software for fighter jets has revealed himself after completing his dreamed-of collection.
He said: “Bill Gates builds a house, Jeff Bezos builds a yacht, everybody has something they want to do. I didn’t really want to buy a yacht because I get seasick. I collect coins.
“It’s my hobby, it’s my release. It’s completely separate from everything I do in business. It’s just something that’s always fascinated me.”
The founder of Green Hills Software, which provides technology for nuclear bombers, is worth around £1.5 billion, and has been collecting the world’s rarest coins since 2005. His 1,000-strong collection of coins minted by this country’s rulers has examples dating back beyond the Royal Mint’s 1,100-year history, and includes currency issued by obscure 7th-century Kentish king Eadbald, and Mercian ruler Offa.
Encompassing currency from the nine-month rule of Harold Godwinson, and surviving pieces from the brief reign of abdicant king Edward VIII, the Tyrant Collection is the largest in private hands and rivals that of institutions such as the British Museum. 
Mr O’Dowd, who ordinarily keeps a low profile because of his military and government work, has managed to keep his passion for coin collecting equally secret. He said: “When you build a coin collection, if you’re too big, and people find out what you are doing, they can hold you up.
“If anyone knew what I was doing, the collection I was trying to build – they could charge me whatever they want. They could extort me on every coin because they would know I needed that coin or I wouldn’t have the complete set. I did it completely in secret. Nobody knew there was even a collection being built, so I managed to get it without being taken advantage of.”
Both the print and online versions include some nice colour photos, including a 1957 sovereign which is undoubtedly a proof version. I was aware that 1957 proofs existed, and have seen at least one previously.
I will now finish reading the print version, to see how many other boobs I can spot. There are more than page 3 of The Sun so far.
 

Anyone mocking Gammon is missing out on great educational videos. Your loss.
Given how the US has weaponized the financial system against their perceived enemies, this kind of reaction from Russia makes total sense. Pricing 1 ounce of gold per 1000 barrels would create insane demand for gold and the demand for physical on a global basis would soar. Russia already has their gold but they'd also be gathering a substantial amount of additional gold by offering this arbitrage opportunity to traders.
It'd be a brilliant plan because it'd wreak havoc in Western financial markets and we'd discover the non-manipulated price of gold or more accurately a manipulated price in a positive direction for gold.
As a holder of gold/silver and mining stocks, I hope they do this.
