A central, complete list does not exist. Larger stocks are kept by specialist retailers like Scription, whose offers and prices, however, are non-binding and quickly changing.

The auction prices stated by Montblanc on its own website often deviate significantly from eBay prices. Generally: some editions like the Hemingway retain their value close to the RRP; others like the J.P. Morgan are to be had under RRP.
