The Market Score is a SetCensus analytical metric derived from current market observations. It is not investment advice.
Market by condition
New is not factory sealed. Used is not a complete-set grade.
New-condition and all-condition asking prices differ widely. This usually means mixed condition or completeness, not a single market.
ASK
New condition
Active eBay listings reported as New. New does not prove factory sealing.
