At a secret location somewhere within the Dallas area, a tennis-court-sized vault exists, filled with all of the coins drivers used to throw in the bucket as they got on and off the Dallas North Tollway. I guess all those coins have to go somewhere, but now that the North Texas Tollway Authority has switched to cashless tolling, the elusive and heavily guarded vault will sort its last coins and close for good this month, according to today’s DMN story.

The story details what goes on in that secret, factory-like vault where workers go through all that change and send it to the bank. OK, so it may not be that interesting. But apparently, losing your wedding ring at the toll booth is quite common. Workers often find those and other jewelry among the coins.

Most of us in the neighborhood probably have a toll tag, so the switch to cashless tolling may have almost gone unnoticed. But, at least some can say so long to lost jewelry and dental crowns. Yes, a dental crown has been known to show up at the vault.
