Each set has the SILVER PROOF coins of the 5 National Park quarters released that year. So inside each package are 5 ATB quarters. With 10 sets, there are a total of 50 ATB SILVER proof quarters in this listing. See photo for an example of how a set looks inside.
The sets are new and directly from the US Mint. They come in their original packaging and with COAs.I will pack with care.
