@NervousNinetales asks
I want to do one proper check of my collection before the year ends. What would you actually check?
Jeff answers
I'd compare the cards you physically have with your records, including versions, quantities, and anything sold or traded. Then inspect the storage area and fix obvious gaps in protection. Refresh references in our app where useful. An accurate, safely stored collection is a better starting point than a dramatic total.
