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.
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?
