2021 Leaf Pro Set Metal

2021 Pro Set Metal Soccer is a one-card subset within Leaf's broader 2021 Pro Set Sports release. The 'Metal' designation refers to a chromium card stock variant; the soccer representation in this Metal subset is limited to a single subject — Cristiano Ronaldo, card #S-01. The parallel ladder for the Metal subset is minimal compared to the broader Pro Set Sports product (which includes Light Blue /4, Orange /3, Navy /2, Purple 1/1, etc.). The Metal version's documented parallels are Blue (often described as 'Blue Mojo' for its prismatic finish) and Orange. PSA 10 pricing for the Blue Mojo Ronaldo trades around $54, with the Orange typically uncatalogued or unsold in our DB. This is not a standalone hobby release — there is no 2021 Pro Set Metal Soccer box. The Ronaldo S-01 was pulled from 2021 Pro Set Sports product configurations. For collectors, the relevance is narrow: a parallel rainbow chase for the single soccer subject, or a completist piece for Ronaldo collectors building cross-product chromium sets. Looking forward, Leaf's Pro Set Metal line expanded in subsequent years (2022 Pro Set Autographs, etc.) into larger soccer-specific products — making this 2021 entry a precursor and curiosity rather than a meaningful hobby release.
