Reading this edition’s market

Compare the same cover, printing and grade before setting a bid. A raw guide or a higher-grade price does not establish a slab’s value. Include selling fees, shipping and the depth of completed-sale evidence when assessing an exit price.

The table includes 8 guide observations and 1 catalog references. These are reference values, not guaranteed sale proceeds.
