A Florida doctor's insane card collection -- featuring ultra-rare Babe Ruth items -- is hitting the auction block following the doc's tragic COVID death ... and experts say it could all sell for around $20 MILLION!!!
Dr. Thomas Newman -- who had been collecting cards since the 1980s -- had amassed the WILD assembly of pieces before he passed away in January at 73 years old due to complications from coronavirus.
The collection is stunning ... there's famous Ruth and Mickey Mantle rookies -- and it also features cards from Honus Wagner, Ted Williams, Cy Young and more.
Newman's family says it's enlisted Memory Lane Auctions in Tustin, CA to help facilitate the sale of the pieces after the doctor's passing ... and experts there anticipate record-breaking prices for the cards.
In fact, one of the Ruth items -- a 1933 Goudey #53 -- could sell for over $5 MILLION, so says auction house president JP Cohen.
"[It] is the finest known of its kind," Cohen said, "and we expect it to break the record of $5.2 million for any sports card."
The Mantle rookie, a 1952 piece with a near-perfect PSA 8 grade, meanwhile, is expected to fetch over $1 million on its own as well.
Auction officials say bidding on the cards is set to begin on June 21 ... and close on July 10.
