The UNUM of E PLURIBUS UNUM in the reverse of 1918-S appears to be enlarged. This is because the area near the pool is slightly raised, so the inscriptions are not clearly stamped, making them look blurry. If you compare it with the same 1918-S, you can clearly see the difference.I sometimes see recent coins, but when I compare them, I can clearly see the difference, so I keep it as a variety item.
