tcdb sid 200571, header "Total Cards: 30", renders 30 rows; cardboardconnection independently states "Keystone Signatures Set Checklist: 30 cards. Serial numbered #/129." UNIFORMLY serial numbered #/129, and that unhedged editorial figure was TESTED rather than copied: the distinct token set over all 30 rows is exactly {SN129} (flagged "AU, SN129"), enumerated in full. The figure is recorded here in words because sets.csv has no print_run column. A set of 1980s-90s veterans, not rookies. Autographed, so set_type=auto.

Checklist · not documented
This set has a recorded count of 30, but the card-by-card checklist is not yet in the catalogue. That's an open research question, not a statement that no checklist exists. If you know a source that documents it, tell us — a pointer to one is exactly what closes these.
