Auction Sales Data: Rarity and Values.

The goal of this Database is to provide collectors with hard data about the rarity and value of pre-pro glasses.  Both can be derived from a knowledge of how frequently glasses appear at auction and their final sales price.  Sales have been logged since August 2001, so the data pool is large and growing daily.

Rarity Index Sales Frequency -- at least:
Very Common Once every 2 months
Common Once every 6 months
Uncommon Once every 2 years
Rare Once every 4 years
Very Rare Once every 4+ years
Only Example Once during life of
database.
