Lot of 6 Vtg American State Souvenir Plate NY, IN, NE,WY, CO and KS all Nice

Lot of 6 Vtg American State Souvenir Plate NY, IN, NE,WY, CO and KS all Nice,  These are all pre-owned but still in good condition.  I didn't see any major flaws such as cracks, breaks, stains chips etc.  Two of the plates have tape on the back but that is the only issue.  I am not exactly sure the age because these are from an estate sale.
