I bought these (set of 5) when they were released in 2010/2011. They were released with quite a bit of fanfare. The mint was testing the demand for 5 ounce silver. Those original 5 were HOT and sold out quickly. The mint subsequently released a bullion version and a proof version of the 56 ATB "coins" at a rate of 5 per year. The final "coin" being the "Tuskegee Airmen National Historic Site" (Alabama) in 2021. I am curious about those original 5, 5 ounce "coins". Does anyone have any information about them? Is there any demand for them - other than bullion? They are: 1 Hot Springs 2 Yellowstone 3 Yosemite 4 Grand Canyon 5 Mt Hood
There were two versions of each, a bullion strike, and a P mint marked "special finish" collector's version. Here's Hot Springs ebay results https://www.ebay.com/sch/i.html?_nkw=hot+springs+5+ounce+coin&_sacat=0&_from=R40&rt=nc&LH_Complete=1 - not much above melt it seems. Same with Yellowstone. Some may fetch more, I don't know.
