I simply do not understand Modern - Doncic vs Mantle

[Rhotchkiss]

I am bored, sitting ay home, and waiting for football to start. So, to pass the time I am looking at every auction house I can think of. I saw a post here that PWCC extended its monthly premier auction last minute, and so I decided to look at what's in that (still open) auction. Really, there is nothing for me at all, as I counted a total of 3 pre-war cards in the whole auction (including a Magie error); its probably 80%+ new and shiny football and basketball with maybe as much soccer as baseball. Anyway....

Here is what I just do not understand: There is a 2018 National Treasure, Rookie Patch Auto, 7/99, of Luka Doncic, graded BVG 9.5, that is currently sitting at $280,000 before Buyer's premium. There is a also a 1952 Mantle, PSA 7, currently sitting at $240,000 before Buyer's Premium.

Luka Doncic has played in the NBA 3-4 years and has won absolutely nothing. Mickey Mantle is a first-ballot HOFer, who played almost 20 years with the Yankees, appeared in 12 World Series and won 7. He is an icon of his era. This Doncic card comes in at least one other exact same variation, except its numbered to 20; I am sure that same pic is on many other Doncic cards. The 1952 Mantle is likely one of the top 3 most iconic sports cards of all time. Not to mention, there are only 75 non-qualified PSA 7 Mantles, with only 56 non-qualified graded higher (close to the 110 of the Doncic RPAs)

How/why is a 2018 card of Luka Doncic worth over $50k more (with BP) than a 1952 Topps Mickey Mantle PSA 7???!!!

I get I am a fossil, and I collect cards of dead guys that many young people dont care about, in a sport becoming less popular with each generation. But I am not talking about an E92 Eddie Collins or even a T204 Walter Johnson. I am talking about a PSA 7, 1952 Topps Mickey Mantle. I simply do not understand and cant help thinking/knowing that the winner of this Doncic (and many similar cards) will take a bath unless he/she flips it ASAP (and I pity the person holding the card when the bottom drops out)
