If you make a statement that "silver is not an investment" while holding gold as an investment, you are making an incongruent argument
As @JohnA1 said, gold isn't an investment as it has zero yield (words of Warren Buffett). If we take an infinite horizon (all available data) then stocks outperform gold by a factor of more than 10. Even bonds, which are "risk-free", outperform gold and silver
Let's be realistic. The Risk-Free Rate is currently 5.19%. In light of central banks hiking rates gold and silver are currently depreciating - those seeking safe havens are piling their funds into Treasuries. If you want a secure investment then buy Treasuries. Of course buying stocks/paper/Treasuries are subject to 3rd-party risk, just as with vaulting gold or silver, and all of your trades are monitored and subject to taxation
The reasons to own both gold and silver transcend markets and investment decisions. It is for security, generational wealth, it is enjoyment, it is numismatic pleasure. You don't invest in precious metals to get rich - to get rich you invest in stocks. You invest in precious metals to not get poor.
Anyone running a totalitarian ratio one way or the other - 100% gold or 100% silver - is taking a naked bet on those assets. It's the same as holding 100% of your investments in GBP or USD. This is a fact that escapes most people. NOT INVESTING in other currencies and assets is taking a huge naked punt. It is diversifying your investments to some degree that is your insurance and your hedge. It is never prudent to invest 100% of your funds or close to it in a single asset or currency. In those circumstances you are gambling, not investing. 
Silver is actually much more lucrative than gold from a re-sale POV. With gold you're buying at 3-5% over spot and selling at 5-10% over spot (assuming you're using eBay or something, not including fees and shipping). There are numerous large businesses who will sell gold at a more competitive rate than you can offer as a private seller. With silver if you buy on TSF or from private sales, you can always offer a better deal than the largest dealers as you have an inherent 20% VAT advantage as a private seller. You have to work a lot harder to make £1500 sales in silver than £1500 in gold (a single coin) but your margin is significantly higher with silver

Hi,
Gold is highly liquid, well priced and if you are thinking about making a turn on buying and selling gold or silver you may be disappointed.
People don’t sell gold cheaply, not can you sell at a great deal over spot unless the market moves.  
 
Gold works best as a mechanism to preserve wealth over the long term.

Nice but i'd prefer the Royal coat of arms if i had to choose .

I can assure you that doing it with gold is much more fun than using silver!...
...and it's such a nice colour. 🙂
