I’ve seen some modern collectors seek out inserts with card numbers equal to the players jersey number. But I haven’t seen # 1’s go for a premium just bc they are #’d as 1.
Ive seen slight premiums, maybe 10-25% over the regular number, with the premium being higher on higher numbered as opposed to lower (ie 1 of 5000 would be more than 1 of 25). Jersey numbers would be much higher a premium, also depending on quantity produced
