Sorry for cross-posting, but I started this in Cop Talk... so reply here or THERE I'm looking for some suggestions, comments or experiences regarding challenge coins. These set would be for police officers, but the info I am looking for is generic to the coins themselves. Looking for pictures, design do-s and don't-s, size preferences, epoxy coatings, colours etc. I've visited the manufacturers websites, so I know what they offer, I am looking for real first-hand experience. Thanks.
