Best for

collectors who already know edition premiums
people completing or pricing Stronghold (143 cards, code sth)
singles buyers focused on Stronghold / Mox Diamond

Skip if

you will not check edition/treatment and still want “NM mythic” prices
you expect every rare in the set to hold similar resale

Common mistakes

On Stronghold, the usual miss is pricing by card name alone without edition (Alpha/Beta/Unlimited/Revised). Money still clusters around Stronghold / Mox Diamond; treating the whole list like one price tier is how people overpay bulk. Also: Stronghold (1998, early Magic) gets mixed into lots that are not the same product — match set code sth before the art.

What to check first

First: edition line, authenticity, then condition. On Stronghold / Mox Diamond, do condition under light before grade talk. Then use the Stronghold checklist for gaps — sealed is not a plan for the expensive row.
