A while back I decided to try to collect any coins I come across with guns on them. I have only found 2 so far after about 30 lbs of bulk foreign coins. You guys have any to share?
Look at the early US Commemoratives, you will see some. And later ones, especially the memorials to war and veterans.
I don't own any, but look for Swiss Shooting Talers. There's a whole lot of them, going back hundreds of years. Some really cool designs.
There are quite a few world coins that have guns on them actually. Some have them prominent on the coin and some, like the Panama Balboas, have them but are very small. Reverse shield upper left has a rifle and sword crossing each other. As seen above Guatemala has some coins with guns as well.
I don't know if silver bullion coins will fit your collection or not, but there are several firearms manufacturers that are on silver tokens. I think I may try a few of those if I can get them close to melt value. They just look cool and I have always enjoyed my guns in my 70 years.
This is not an area I ever paid any special attention to, but in looking through some coins I have scans here are a few. I agree there are a lot of coins with guns on them. I just don't happen to have pictures handy. One of them is showing twice but I can't get it off.
