About the JustCollecting British Rare Stamp Index:

The JustCollecting British Rare Stamp Index (Mint) tracks the performance of 30 of the rarest British stamps in mint condition, using analysis of major stamp catalogues (Stanley Gibbons/Scott/Yvert/Michel) measured against confirmed sales at auction.

Values shown are reflective of 'very fine' condition examples, without fault, in the expected condition of 'hinged' for earlier issues, upgraded to 'unhinged' for later issues.
