Such a coin does not exist. The Threepence was not introduced into the British currency until about 1550.
The dodecagonal (12 sided) British brass Threepence was first issued in 1937. The Edward VIII coins dated 1937 were never released into circulation and were melted down. Some coins given to vending machine manufacturers for testing purposes, were never returned. The official first release of the brass Threepence was in 1937 with George VI.
The British Edward VIII 1937 Threepence, which was never issued, had the 3 interlocked rings design on the reverse.
Please check your coin. Edward VI died in 1553. There were no British 1937 Edward VIII coins issued with his name or likeness on them.
The British Threepence is part of a redundant currency that was withdrawn and demonetised in 1971. It no longer has an exchange rate with other currencies.
Modified coins have no collector value. The ring may have some value.
The Royal Mint produced no British Threepences from 1801 to 1833 inclusive.
The 12 sided British Threepence issued from 1937 to 1967 inclusive was made from a nickel-brass alloy. The small silver British Threepence issued from 1920 to 1945 inclusive were made from an alloy of 50% silver, nickel and copper. Although the silver coins were circulated in Britain, they were intended for use in several of the British Colonies.
British Threepences have been minted for hundreds of years. Any collector value would depend on the year and condition of the coin.
The only British 1831 Threepence issued was the Maundy Threepence. A British 1831 Maundy Threepence (FDC), uncirculated and in absolute mint condition could fetch up to £40 GBP. If it has been circulated but still in good condition, it might fetch up to £20 GBP. A reputable coin dealer will be able to give a more accurate valuation.
