Modern minting technology minimizes the amount of coins, together with safeguards to reduce the creation of such mistakes, and to improve the likelihood that, when created, they are discovered and removed before going into the coinage supply.

For these reasons, a triple-struck 2015 Australian dollar was an eye-catcher one of the items being provided in International Auction Galleries’ March 20 and 21 selling, the company’s 93rd.

The mistake is in Uncirculated condition, according to the auction house based in Queensland, Australia.

Doubling of the design and lettering is present.

Based on the auction house images, Mike Diamond, Coin World columnist, said that,”This Australian 1 penny coin doesn’t appear to present any mysteries. The obverse die (Queen’s heartbeat ) was the hammer die. The coin obtained at least 2 closely-spaced, well-centered strikes. The first strike occurred in a partly installed collar (a partial collar error). I suspect the following strike(s) occurred from collar (a broadstrike).”

That explains two of the strikes, but the third one is more cryptic, at first glance, he said, before seeing the coin’s edge.

“The advantage of the coin may have been nicked by the expires following these strikes were finished,” according to Diamond. “Quite simply, a final, much off-center strike.”

One of U.S. coins, such errors are well represented, but by no means common, Diamond told Coin World. “I really don’t know how common they’re one of Australian coins. A similar error on a U.S. coin wouldn’t sell for as much as this one is anticipated to realize,” he said.

Diamond said,”A Sacagawea, Native American, or Presidential dollar with a similar error would struggle to split $1,000. Lower denominations would be worth much less than that.”
