Jim...From what I understand the Plaza Silver Strikes are still in the machines. I made several inquiries at the Hard Rock after the convention. They all had the same info 500 made there may be a few extra samples made for gaming approval etc. but 505 to 510 at most. Cashier needed a coupon to account for every chip etc. If there is more out there than this it's yet to be uncovered. It pays to have a spouse who is an associate member. My extra went to Fran in Spain who Bob Hermans & I agreed deserved to know we looked forward to seeing him next year. What is posted here is the selling prices etc. but more than a few of these coupons were given to collectors by people who preregistered & didn't collect in this area. The stories you see posted are the ones about collectors or dealers buying the coupons for $25, but I'm telling you I saw many given away to others sharing the hobby. If there was a way to get the true stats I'll bet that more were given away than sold.
Just my opinion.
