One modern couple couldn’t make heads or tails of whose last name they’d use upon getting married.

So they flipped a coin.

Jeff Conley and Darcy Ward decided against the tradition of the bride taking the groom’s last name in the name of equality. But the Florida duo took the concept a step further by leaving the decision to 50-50 chance.

At the altar of their Dec. 14 wedding, they flipped a brass, engraved medallion, one side with Darcy’s last name, and the other with Jeff’s surname.

“It’s fair. I am a graduate student in economics at Florida State and I think about fairness,” Jeff told the Palm Beach Post.

“Being with someone who was willing to start the marriage from a creative and teamwork and fair place felt like a really good first step toward an equal partnership,” Darcy, a nurse-midwife, added.

When the time came, it was Darcy’s name that won out. Mr. and Mrs. Ward were thrilled with the result.

“You could say I won,” Jeff said. “I was the one who received something new.”

It wasn’t the only way they ditched outdated marriage customs. The two, who met on Tinder, proposed to one another with separate surprises: Darcy with a scavenger hunt — complete with her getting down on one knee — and Jeff with a live musical serenade of their favorite song, The Band’s “The Night They Drove Old Dixie Down.”

Couples are increasingly bucking traditions on their wedding days, from celebrating their union with matching Mr. and Mrs. bongs to ditching their new spouses altogether and embarking on “unimoons,” or separate honeymoons.
