I have cards that are numbered because they are limited to number of copies issued that would have a premium value
I have limited edition cards that are numbered (example, 18 of 99) which makes the card more valuable than the base versions of those cards. I don't see a way other than using notes field to record that premium to the card.
We should track print run numbered cards separately from the base cards without a print run listed.
If you let me know the card I can looking into this to see if we have the correct one, or if we need to add it.
You shouldn't need to add the print run to the notes field in your collection. You can keep track of which specific number you have, like 18/99 instead of just seeing the /99 part on the product info.
