hi all - just wanted to know what size gold coins have the largest diameter as im looking to make myself a coin ring out of it - was thinking 1/2 US gold coins? for a good size
Air-Tites has a list of all sizes for every kind of coin- http://www.air-tites.com/coin_size_chart.htm#.VXzNU1LXenM
Just looking at that it does not list the 4 Ducat which has a 40MM diameter. Nice coin. Edit - yes it does. Doh.
