The grading company would only say it is grade C because it was yellowed and slightly stained. Sure, it is a bit unusual item to collect and probably doesn't look any pretty on the shelf so $1000 might be adequate. On the other hand, various trading cards such as Magic the Gathering, Pokémon and others were mass produced in large quantities - obviously some on purpose less common than others - so I think $1000 would be adequate for one of those as well. Definitely not $50000 which is a price tag I associate with true antiques.

This was part of a Swedish game show where the competitors get to guess which out of a half dozen different objects is worth the most - ranging from $50 to $50000 and the item they "keep" in the end equals the amount of money they win. I'm sure it is an imported game show format that exists in many countries. Previously they've had Nintendo 64 games on the show, next to the paintings, furniture, memorabilia etc.

^Cool!  We don't have a game show like that (exactly),  to my knowledge...Although there was something similar,  where (I think, not certain) the competition was to get a storage unit that was worth the most based on what was in it...

Wow! I just learned that Bytt är bytt indeed is an original Swedish show, not an imported format like most other popular shows tend to be. Per IMDb, this show instead was exported to the Netherlands in 2015 and has the English title "Trash or treasure" though I'm unsure if it was broadcast in any English speaking country.

Broadcasters

TV4, Sweden (6 seasons and still on air)

DR, Denmark

SBS6, Netherlands

DeeJay, Italy

ABC, USA (pilot)

so there was at least one pilot episode even if ABC didn't buy the format.
