For investment purposes, buyers can choose some of the older British silver coins or new and popular silver bullion coins. Examples include:

1. The 10 ounce Silver Queen's Beast Unicorn Coin proof. There are ten different designs in the Queen's Beast series. The proof coin should come with a certificate of authenticity (COA) to ensure you're getting the real thing. This enormous coin has 10 Troy oz of .999 pure silver and is limited to an 850-coin mintage.
2. The 2017 one kilo proof Queen's Beast Lion Coin is one of the most valuable coins in the series. It has a face value of 500 pounds and contains 32.15 Troy ounces (one kilo) of .999 pure silver. The mint released only 600 of these coins.
3. The 2007 Abolition of the Slave Trade Two Pound Silver Proof Coin has an erroneous inscription on the edge of the coin which reads "United into one Kingdom". It's not known how many coins have this mistake, but these error coins have recently sold for 1,100 pounds or more.
4. For investors who collect older coins, there's the 1899 Great Britain Silver Maundy four coin set. It was initially released by the British Crown on Maundy Thursday, the day before Good Friday.
5. The 2016 one ounce Silver Monkey coin is a good option, particularly if you have a limited amount of money to invest. It is 99.9 percent pure silver and has a proof-like sheen. The coin has a face value of two pounds and a Mint State 69 grade from the NGC.
