Guest Stephen Okano Posted August 17, 2021 Report Share Posted August 17, 2021 I just started entering my USPS Commemorative Stamp Panels into my database and I noticed that there are two scott numbers. The later numbers start with a "CP" followed what I assume is the USPS Commemorative Panel Number (if it is, it is one number off). My question is when will this inventory of USPA Commemorative Stamp Panel be updated? Quote Link to comment Share on other sites More sharing options...
