It is a liquidation platform for the US government to recoup funds from lost mail. This Auction: https://www.govdeals.com/index.cfm?fa=Main.Item&itemid=91394&acctid=4703 just concluded which features a ton of booster boxes, slabs, a southern island binder, and many many other cards. This auction not only consisted of Pokemon, but of Sports and other collectibles. Do you think this person bought more than 23K worth of items?
i bet its a lump lot of a bunch of lost items sold as one lot, not one huge package lost. second thing i don’t see how this lot is worth 23k, im not seeing anything super valuable over 10k.
Looks like your typical collect a con vendor stand haha!
