I checked several magic shop sites and they were asking from $42 to $48 each for these same coins.
Also, I would suggest that you buy some new Kennedy halves from USMint.gov to match your mag coins.
I had some older half dollars that were older, more worn and less shiny than the two Super Strong
2013 coins I purchased. The US Mint coins are uncirculated, so by using them along with the mag
coins, attention won't be focused on the mag coins as being so different.
