That would not surprise me. It seems that many with mint orders on backorder status will likely lose out and need to go to the secondary market. There are some eBay auctions closing soon that are ripe for the picking before it goes over $100. Once graded examples start to show up, the raw sets will also get a boost.
Just went from backordered to currently unavailable. Officially sold out now? Glad I got 12 more ordered last minute!
Currently unavailable (aka Sold Out): http://catalog.usmint.gov/2015-marc...&_ga=1.49097126.1842528881.1431456945&start=1 Good luck on eBay. Some sets are still reasonably priced in auction. TC
Where does the 'available in August' information come from? That is poor business practice from the Mint.
