OldSilver

I am very new to collecting and I have a question about the $10 British Virgin Islands 1900 - 2000 coin issued in 2000 1 oz silver coin. The only examples I can find online have no gem insert and I'd like to know how rare or valuable the coin is. So does anyone here know where I can find such information. ... I also have a £2 South Georgia & south sandwich islands 2000 1 oz silver coin which has the crown crest and celebrates the queen mothers 100th Birthday. It also has a small gem insert.
