It really depends at what grade the coin will trade. It may or may not actually be MS-64. Here's a link that speaks about the company that graded this coin: http://www.heavypen.com/coins/page4.html The blurb on this particular company is partway down the article. I would say it's reasonable that this coin is at least AU, and we'll give them the benefit of the doubt and say MS-64 is the top of the range. That puts the retail price in the $125 - $200 range, with a likely dealer buying price of $95-$140.
