I would have bought it because I am interested in making custom rounds soon; however, I am saving them up for a little something something for myself.
If you're making custom rounds I highly recommend buying some scrap silver. I make my own bars/ingots, too. These coins were 80% Silver, which means 20% of them is not silver. Its an alloy of copper, and possibly nickel or zinc. What's easiest and most profitable I have found is 925 silver. Jewelry is made of 925 silver (Sterling Silver), and so there are tons of lots on eBay with broken jewelry, etc. Since its higher in silver content, it melts at a more reasonable temperature. Most silver rounds though are made of .999 silver. You can buy silver shot (tiny beads of .999 silver). Although, I have made some custom bars for people (they like the hand-poured look), and believe it or not the best way to obtain your silver for that is to go to your local coin store and ask to buy just one of the junk rounds they have for sale. At my shop these are priced 75cents over spot. It may seem weird/stupid to people to melt down already minted silver, but if you have a plan for it, why not. I would much rather have a hand-poured 3oz bar than 3 crappy old silver rounds. Although, you have to realize if you do that you are holding onto silver for the longterm, for investment-because people are hesitant to buy something that a professional mint hasn't made.
Anyways, good luck in your pursuit of creating custom rounds. I'd be interested in seeing what you come up with. Last piece of advice: use PLENTY of Borax. .999 silver especially likes to remain stagnant in the crucible. Borax is like PAM for your crucible. And buy it at the grocery store (detergent aisle) and not online as a "silver flux"
Good luck.
