First Sapphire subset year
2023-24
Serial / scarcity
Unnumbered
Collectability
Infinity is a chase lane first; the parallel tree matters because collectors already separate the insert identity from ordinary Topps Chrome Sapphire Edition color.
Value read
Useful as an insert/subset reference, but do not price it like numbered color without proof of short-print demand.
Common trap
Treating an unnumbered insert parallel like confirmed scarce color.
Audit basis
