Artist-Signed Cards: What value should I expect?

Most vendors consider artist-signed cards to be Heavily Played or Damaged condition (regardless of actual wear and tear) and will not purchase them. The vendors who do purchase signed cards will only buy them if in Near Mint condition, and even then they will downgrade their buy price (typically applying their Lightly Played or Moderately Played price). Typically we don't recommend sending them in to our service, as there is a risk they will not return much value, but we will of course process them to the best of our ability if you choose to include them in your shipment.
