Looking for some advice on folding coins (2 fold). Are the Roy Keupper coins the ones that have a groove all the way around the coin or are they the internally drilled ones (or both??). I don't like the ones that have the groove around the hole coin as it can be seen even through the green glass of a bottle.
If someone could advise where to get the internally drilled ones that would be great (any currency or AUS).
