I recently bought a large collection of very old Magic cards. While sorting through them, I found two cards that I don't have an immediate answer for their value.
(Promo from the first Pro Tour, in 1996)
(Autographed Blue Ward (might be Dan Frazier, revised))
Google / magiccards.info didn't have any information.
tcgplayer.com came up with this result, a 'Collectors Edition' Winter Orb, but that page says that the card type is 'Continuous Artifact' and has different text for the ability.
Is there a concrete way to determine the values of these cards?
