But as people stayed home and businesses were closed because of the coronavirus pandemic, the amount of change in circulation has been drastically reduced. Casinos, banks, and coin-operated laundromats have been hardest hit.

Now, the newly reopened casinos are being forced to come up with creative ways to combat the coin shortage after months of lockdown.

Before the pandemic, El Cortez had $120,000 in nickels, quarters, 50-cent pieces and dollar coins. After the casino shut down in March, it deposited all but $30,000 worth of coins at the bank, according to the Las Vegas Sun.

Getting those coins back has been difficult.

"Our first coin order that we did after reopening, in July, we ordered $30,000 in quarters," El Cortez manager Adam Wiesberg told the newspaper. "When the Brinks people came, they brought us just $500 in quarters. That's when we realized firsthand that there was a coin issue. We're fortunate we kept that $30,000."

A model adopted by The Cosmopolitan of Las Vegas in July 2019 might provide a way forward for some resorts. Customers can choose to print tickets to receive their change or donate to one of four rotating charities, helping worthy causes and saving the casino from dispensing precious quarters, nickels and dimes.

"Since we reopened our doors following the mandatory COVID-19 closure earlier this year, we have seen record numbers in both the number of transactions and in monetary donations," said Chelle Adams, chief financial officer of The Cosmopolitan. "We are immensely thankful and proud of our guests' efforts in wanting to support our community throughout the trying current climate."

The casino has also encouraged its employees to bring in their loose change to cash in for no fee. For every $60 worth of coins employees bring in, Adams said, they are awarded gifts through the casino's internal rewards program.

The D Las Vegas, home to the Sigma Derby slot machine, where gamblers can use quarters to place bets on five mechanical horses, has another approach. It is running a promotion called "I helped save Sigma Derby."
