The coins I get for my son are Royal Mint are proof silver bullion. Thanks to brexit silver and gold bullion prices are in a slump, it’s time to buy but don’t expect a quick return.
Do not buy from the Royal Mint, there’s better deals if you shop around. I’ve just bought five 2 troy ounce “Queens beasts” coins as a set for far less than the mints rate.
1 troy ounce = 1.0971 avoirdupois ounce.
1 troy pound = 12 troy ounces.
