<p>[QUOTE=&quot;ClairHardesty, post: 1304140, member: 34169&quot;]Don&#039;t forget that along with all of the other variations, die are replaced on a fairly regular basis and even with modern production techniques, there are differences from one die to the next. I don&#039;t know exactly how long the average die pair for bullion SAEs lasts, but even if we give it an optimistic 100,000 coins, the west Point mint will use up more than one die pair every day this year. The 2 or 3 million SAEs that were minted at SF in the first run this summer clearly went through more than a handful of die sets. Everything from early die state to late die state coins are minted every day. Also, you would need a fairly large sample size from the two mints striking the bullion coins, and need to do an analysis that shows two distinct populations before concluding that you could even begin tell the mint of origin by looking at an individual coin. In the end, you&nbsp; probably can&#039;t. Even if two populations really exist, they probably overlap enough that it would not be statistically possible to say with any certainty where an individual coin came from. Traceable provenance is really the only way to tell, whether guaranteed by an labeled encapsulation or some other means, like the ones in the 25th anniversary sets, which have the published statements of Tom Jurkowsky.[/QUOTE]</p><p><br /></p>
