I have been given 4 Australian Mint gold coins and one has a red mark on Queen Elizabeth's chin. Will this bring the price down? Also are they worth selling as a set or individually?
Cheers these are the photo's is it unusual for Perth Mint to make an error or be sloppy in there colouring with a coin. Apologies for this large one not sure how to make it smaller on here.
The red spot is actually a little bit of copper in the coin. It's not common but its also not unusual to find in gold coins.
