I am going to be getting some silver britannias, I am thinking of buying coin capsules for them. I like the idea of protecting the coins. A few questions:
1. Can coin capsules themselves damage the coin in any way? (Milk spotting etc)
2. What are the best brands to buy?
3. Where can I buy these cheap?
Some google searches show 39mm ones for the britannias, some 40mm. Can someone please confirm which size is best.
P.S. Complete novice at the moment and new to the forum.
I must say that this is one of the most informative places for silver on the web.
