A couple of years ago, I was on a roll finding U.S. Mint Sets for below face value on eBay. Worst case, I could cut up and spend the coins for a profit. I ended up doing that to many of the coins while I built nice collections of some and sold others. Below is a photo of Eisenhower (IKE) Dollars I purchased for about $0.80 each. Several of these are still in my collection today.
