I have been slowly adding in the SN for every card that my PC player is in, as I find a copy for sale. There are 81 cards that include that player and I'm sure some players have a lot more than that.
This is a very slow process and because a large number are below SN10, they may not all show up for sale. There are only a few sets and the gold parallels that are known 1 of 1's.
At least they provided the maximum SN for each parallel because some are hard to determine based on photos alone.
I messaged Leaf a couple of weeks ago with no reply.
If I had this information I would update all the cards, but it would still take a long time.
