What Constitutes A "Master Set" Today?

[swarmee]

For most modern set collectors, parallels of the base set are not usually considered part of the master set.

Like for Allen & Ginter (not Ginter Chrome or Ginter X - two other sets that reprint ginter on chrome stock or where the cards are black), a 2025 collector would likely call this a Master Set:
Base set 1-350
EXT Mini set 351-400 (usually - some years they get these wrong)
All base Mini framed autos & regular sized autos (usually, these have different people on them)
All base mini framed memorabilia cards
All base insert/subset/mini subset cards, even boxtoppers
All Rip Cards, and now oversized Triple Rip cards - these are what the EXT Mini set come out of, as well as numbered autos (Parallel, so doesn't count), sketches (1/1 so don't count, not checklisted), stained glass minis (Parallel, so doesn't count), and micro mini parallels (don't count).

At least, that's what I would consider a Master Set of Ginter.
