2013-S US Mint Silver Proof Set (SV8)
This set contains 14 coins in proof quality, protectively encased in three clear plastic lenses and newly designed packaging. The 2013-dated quarters, half-dollar and dime are struck in 90 percent silver, generally referred to as "coin silver." The silver in these coins can be seen by viewing the edge of the coin in the lens. Source: USMint.gov
