<p>[QUOTE=&quot;SPP Ottawa, post: 1530389, member: 39508&quot;]Actually, when I visited North Dakota for a conference and a field trip a few years ago, we spent one night at a casino. I am not a gambler, so I just played with the nickel slot machines - I was amazed how quickly modern coins were wearing down in that environment. In Canada, the pure nickel 25c coins at casinos wear preferentially on the rims, essentially removing the reeding. </p><p><br /></p><p>So, to throw it out there, would heavy casino use be considered natural circulation wear?? If so, then modern lowball coins are possible, without &quot;cheating&quot;.[/QUOTE]</p><p><br /></p>
