Define "stupid."
Remember, to a lot of the general public the whole idea of collecting baseball cards and sports memorabilia is stupid, and when we're talking about game-used items we're basically talking about used sporting goods. To those people, the only reason such items are worthy of having is because they're worth money. A casual baseball fan might not care about Pete Alonso's 52nd home run baseball, but tell them it sold for over $27,000 and they'll take notice.
We here at Net 54, of course, know otherwise. We appreciate the intangible "aura" of a game-used piece.
For my part, I like to be silly and point out ordinary items used in a ballpark that, if slapped with a MLB authentication sticker, officially become pieces of game-used sports memorabilia. Perfect example: this ordinary HDX Sprayer bottle, presumably used by a Citi Field grounds crew man prior to the 7/15/18 Mets v. Nationals game. (I say "presumably" because I didn't actually see it being used; it was just sitting there when I got there, but it's reasonable to presume that it wasn't put there for display purposes.)
Yeah, I'm just having some fun with it. But there may be someone out there who'd think it's a cool item to have... you never know.
I don't think anything can really be "stupid." Silly, yes, as in the example just described, but not "stupid."
