This is a really beautiful coin. This coin is an 1891-S Seated Quarter. It is in a slab by PCI. They give the coin an uncirculated grade, and it definitely is.
The coin is so nice, that I think it deserves to be submitted to NCG or PCGS. The item "1891-S US Seated Liberty Quarter 25c BU Ucirculated PCI" is in sale since Sunday, May 16, 2021.
