The Celebrity Memorabilia Index

Welcome to The Celebrity Memorabilia Index update for January 2023.

Each month we analyse global internet search volumes and present figures in a '3 monthly' and 'Year-on-Year' table to indicate whose memorabilia is popular and whose isn't.

We combine this data with worldwide auction price realisations to determine average prices for a very fine grade 10" x 8" signed photograph, or (for more historic items) a signature on card, as a benchmark figure for the index.

January 2023 update:

With Steve Jobs listed as the world's most valuable autograph we decided to research all the known examples of his autograph and have compiled the definitive list of Steve Jobs' autographs. 

We found there are just 19 examples known to exit

And Tiger continues to march.

Following the sale of his first professional hole-in-one golf ball for $186,000 collectros are now going crazy for the score card that accompanied the round.
