what is the 1981 royal wedding commemorative crown worth
1000
The Royal Mint does not issue Commemorative copper coins. The only Queen Elizabeth II commemorative coin issued in 1953 was the cupro-nickel Coronation Crown.
The coin you have is a Churchill Commemorative Crown and NOT halfcrown. Worth around 50p - £1 today (they were mass produced in 1965....just under 20 million struck in cupro-nickel - an alloy of copper and nickel).
Sovereigns are made from 91.67% gold and are not plated. There were no Sovereigns minted in 1953. Queen Elizabeths Coronation commemorative coin was the 1953 Crown which is made from a cupro-nickel alloy. Modified coins have no collector value.
Commemorative circulation coins were not issued in Queen Victoria's day. Crown coins issued from late 1887 to 1892 have what is known as the "Jubilee" bust of Queen Victoria. It is very possible that you have a commemorative medallion or some other type of souvenir of the occasion.
What is World War 1 Commemorative worth
I believe it is worth 150,000.
There are 4 Isle of Man 1976 Commemorative Crown coins. Two are silver, two are copper-nickel. The silver coins coins are 0.9250 silver, as close as you are likely to get to pure silver.
Nothing because while it is a commemorative medal it does not seem to commemorate anything.
The current value of the coin is approximately R60-R90. +- USD 10.00
