<p>[QUOTE="Conder101, post: 4543628, member: 66"]First step would be to find someone who has an XRF gun and have them shoot it. Best place to find someone who has one would be jewelers that buy scrap gold, large pawn shops, or a larger "we buy gold" establishment. The guns aren't cheap so it needs to be someplace that does a lot of volume to justify their cost. Another possibly location might be a scrap yard but you have to be careful there, some use a different type of tester that actually uses an electric arc to vaporize a sample for testing. It would allow for a deeper test than an XRF gun, but it is destructive to the coin.</p><p><br /></p><p>If an XRF gun result shows a significant antimony response then it would be worth sending to a grading service requesting a composition analysis.
