Subjekt-4 Posted August 8, 2017 Share Posted August 8, 2017 I'm trying to figure out if the serial numbers on the signature series are unique per comic or are there duplicates as well. I ask because I found a cover I like that happens to be signed by Stan but looking for info on it I found one on eBay for way more with the same exact serial number Link to comment Share on other sites More sharing options...

Can you give us some more to go on? The ebay listing number maybe, or a picture? If you mean the CGC case serial number above the barcode, they are unique.
