Unopened 1948 Bowman Baseball headlines MHCC auction

A stash of unopened packs of baseball, football, and basketball cards, headlined by 1948 Bowman Baseball, are available in Mile High Card Co. auction.

By Bert Lehman

It was a phone call that every auction house hopes to receive.

While on the phone with another client, Brian Drent, owner of Mile High Card Co., was interrupted by one of his employees who told him he had to take the call on the other line. Since the call he was on was important, Drent hesitated.

Then the employee handed Drent a sheet of paper that contained a listing of unopened wax boxes for different trading card products from the 1950s and 1960s. At the top of the list was 1948 Bowman Baseball.

Drent said he immediately told the person he was on the phone with that he would call him back and explain everything later. He then took the call on the other line. On the other line was a person who does some consigning with Mile High Card Co., as well as the person who owned the plethora of unopened vintage trading card products that was on the list.

In addition to the 1948 Bowman unopened packs, other items included: 1961 Fleer Basketball full unopened wax box, 1961 Topps Football 5 Cent pack full unopened wax box, 1962 Topps Football nearly full unopened wax box (20/24) packs and 1962 Fleer Football nearly full unopened wax box (19/24) packs, along with several other full and near full wax boxes, each authenticated by BBCE with grades ranging from NM to MINT; 1959 Fleer Ted Williams full unopened wax box, 1960 Fleer Baseball Greats nearly full unopened wax box (20/24) packs, 1961 Fleer Football full unopened wax box, 1961 Fleer Baseball Greats nearly full unopened wax box (20/24) packs, 1961 Nu-Card Scoops near full unopened wax box, 1961 Topps Baseball Stamps Album full unopened box, and 1961 Nu-Card Football near full (17/24) wax box.

Drent was told the cards were originally purchased by a family who owned a company that printed non-sports cards. Drent theorized that the company was thinking about printing sports cards, and the boxes of cards were purchased for research and development reasons. The cards were forgotten about until they were found at the caller’s aunt’s house.

After obtaining a complete list of the unopened product that the person on the phone had, as well as the history of it, Drent told the caller he was interested, and asked the caller what he wanted to do.

“He said, ‘Well, if I was you, I’d get on a plane and come here,’” Drent said.

Drent was on a plane to Tennessee the next day to personally look at the unopened product.

“I walked in the house and he had it all arranged on white towels on his dining room table,” Drent said. “I walked in and I was awestruck.”

Drent said that 20 of the 24 packs were in the 1948 Bowman box, but the seal had broken on one of the packs, which turned out to be a good thing. The packs and box contained the words “Play Ball,” but had nothing on them that identified the product as 1948 Bowman. Being able to see the cards in the pack that the seal was broken helped identify the product.

“There are no known examples (of unopened 1948 Bowman Baseball packs),” Drent said. “There’s never been a pack graded by PSA. There wasn’t a pack graded at the time when GAI was grading unopened.”

Drent added he hasn’t been contacted by anyone disputing his claim that there are no other unopened 1948 Bowman Baseball card packs in existence.

Back to the pack with the broken seal, Drent said that pack contained five cards – a Warren Spahn rookie card, two Phil Rizzuto rookie cards, and two Walker Cooper cards.

With only 48 cards in the set, Drent said he thinks every pack could potentially be like that.

“No matter how you look at it, there are only 48 cards in the set, your odds are amazing,” Drent said. “You have six Hall of Fame rookie cards in one set.”

The starting bid was $50,000 for the 1948 Bowman Baseball nearly full unopened wax box (19/24), but bidding took it to more than $120,000 within an hour of the auction opening, Drent said.
