2022 Brixton Golden Era is a disc golf set that has an insert set called "Historix".
https://www.tcdb.com/Checklist.cfm/sid/387736
The Historix set has a print run of 100 with printed serial numbers. Each card in the set has a version that has a correct serial number /100, and another version that has a correct serial number /100 and another serial number /25 that shouldn't be there. I've attached a photo of some examples. I think each card in this set should have a listed correct variation(correct serial number only) and an error variation(two serial numbers printed on card), but I want to make sure that is correct.
I'm also not sure of the correct/best way to update the checklist to include these variations for each card. I know I could simply do an inaccuracy report and let someone else do it, but I am also interested in learning the site and the correct way to make changes like this.
