I know it can be annoying to have a lot of days on auctions, but that way enough people will come across it so they have the chance to bid and people will have time to gather their credits so they can bid. Sorry :(
Yeah the ones that aren't mint are probably near mint or slightly played int Magic the Gathering terms. But yes, not all if any are mint. So it might be worth a little less than $25. Didn't really put that into account
