Prewar and Modern Question

[Rhotchkiss]

I love me son Oliver, who collects modern. I am his benefactor and I like having a hobby together. As a result, I indirectly collect some modern (through Oliver). My rules are simple -- only blue chip players/positions and only quality products, ideally with a signature on card, and NO base cards. At this point, his collection is substantial enough that he wheels and deals on his own at shows, but sometimes I need to kick in. Right now he is collecting Mbappe, Giannas (I wont event try his last name), Trout, and many of the good young QBs.

Funny, true story -- a couple years ago, at the Philly show, I argued with him over some red wave, prizm bullshit rookie card of Jonathan Taylor, which was around $900. Here is the conversation:

Me: "You want an RB? I will buy you the best Walter Payton Rookie we can find for $900".
Oliver: "But if Taylor wins MVP his card will be worth double ($1,800)."
Me: "Well, If that happens, will you sell the card"?
Oliver: "Yes"
Me: "And what will you do with the money"?
Oliver: "Buy a real nice Walter Payton Rookie"

No Joke -- insert guy with hand on his head and guy shrugging shoulders emoji

Me, no way Jose do I buy modern, and to me, modern is anything newer than 1980. In fact, almost everything I own is at least 100 years old.
