I have been given a scan of a Delta Charmeleon:
The date in the metadata is 2024-7-10. The printer serial number matches the one in the OP.
I have also been given a scan of an alpha Clefairy Doll:
It has a complex dot pattern:
I suspect it could be two dot patterns in one print. When I overlay the dot pattern found on many other alpha cards (shown in white, slightly offset; example is here: Many of the Pokemon playtest cards were likely printed in 2024 - #18 by pfm) you get this:
When you overlay the serial number and year pattern from the OP you can see this:
My hypothesis is that an alpha Clefairy Doll was copied/scanned (picking up the alpha pattern) and then printed on the same printer as the examples from the OP and the Delta Charmeleon.
