Blanton's "minis" have been produced with many slight variations over the years
Generally there are considered to be 5 types of Mini's. 93 Proof USA bottle, 93 Proof Japanese, 80 Proof Black Japanese, 80 Proof Green International, and 80 Proof Korean (lesser known). Within many of these there are slightly different variations, primarily with the jockey position and casting quality.
The list below is a work in progress. Likely exact dates of production for many of these will likely never be known. It is also likely that similar to the larger bottle stoppers, several "types" were used simultaneously. Rarity by "type" is also difficult to determine. in general the Green Mini is considered exceptionally difficult to find while Black is also quite rare.
