The United States flag shown in the photo above was flown on the boat that brought the first American troops to Utah Beach on June 6, 1944, a date otherwise known as D-Day OR the largest seaborne invasion in the history of mankind.

And while the tattered 48-star Old Glory may seem a little tired and worn out, looks can be deceiving.

This one-of-a-kind relic from one of the proudest days in the history of the U.S. recently sold at auction for a whopping …

… $514,000.

The sale took place in Texas and was conducted by Heritage Auctions.

This from the Military Times:

The pre-sale estimate for the flag was $100,000. The banner has one bullet hole, blamed on a German machine gun, according to the Dallas-based auction house.

Online bidding began about two weeks ago, according to [Heritage spokesman Noah] Fleisher, ending Saturday night with a top bid of $125,000. Live bidding started Sunday at that level, he said.

“It opened at $125,000, so obviously spirited bidding brought it up to the price,” Fleisher said.

According to the house, the captain of the D-Day boat that hoisted the flag on its stern was Lt. Howard Vander Beek, from Cedar Falls, Iowa. The combat veteran held onto the artifact until he passed away in 2014, and was subsequently sold at an initial estate auction where it was acquired by the most recent seller.
