DENVER (KDVR) – From the outside, the Denver Mint may be just another two-story government office across from Civic Center Park. But inside the Cherokee Street building, staff and machinery are busy pressing metal coils into millions of coins per day.

According to the Mint, it’s one of two facilities responsible for making circulating coins in the United States – making it a huge part of the nation’s coin flow.

According to Tom Fesing with the Denver Mint, the facility produces roughly 4.5 million coins every 24 hours. Fesing estimates that about $750,000 to $1 million has gone through the facility each day this year.

That said, the Mint can’t exactly predict how much is going to be produced throughout the year as the number of coins depends on the orders the Mint receives monthly from the central bank, the Federal Reserve System, Fesing said.

Despite the millions of dollars in coins passing through, Fesing said the coin with the lowest value, the penny, has historically had the most production.

Those numbers depend on how many coins are needed for cash transactions in the economy, according to Fesing.

“When someone gets back a cent in change, what happens to them? They usually end up in piggy banks, or in a jar, and they’re not introduced into circulation as fast as, let’s say, a quarter or a dime,” Fesing said.

While the Mint can’t predict the numbers for the end of this year, it has produced almost 1.3 billion coins this year, with almost 800 million being pennies. In 2023, the Mint produced around 5.65 billion coins for the entire year.
