Thanks for the advice.
edit: And thanks for yours as well, @CLWheeljack.
The only reason I know it’s worth anything is because I ran across it in one of those articles about the most expensive collectible video games, where a sealed (and graded) copy reportedly sold for $12,500 maybe 10 years ago…I can’t find the article now, and I realize those kinds of articles are a dime a dozen, so it likely wasn’t true anyway.
