Rare dime unnoticed for decades expected to fetch over $500K – is one hiding in your wallet?

A rare dime hidden for decades is expected to fetch half a million dollars at auction. But Americans are unlikely to find one in their wallets.

The coin, struck in 1975 by the U.S. Mint in San Francisco, is one of two coins known to be missing the “S” symbol for the city.

The other was sold at auction in 2019 for a whopping $456,000, and again a few days later for $516,000 to a private collector. AP News reported.

Ian Russell, President of GreatCollections, the specialist who auctionbelieves the coin could fetch $500,000 or more.

“The coin market is strong and there has been a lot of interest in this coin since we listed it a few days ago,” he said. Fox Business.

Coin collectors have long known of the existence of these two rare dimes, but their whereabouts have remained a mystery since the late 1970s.

In 1975, the San Francisco Mint produced over 2.8 million uncirculated six-coin “proof” sets, which sold for $7.

It wasn’t until a few years later that collectors noticed that two dimes from the set were missing the “S” mark.

Three sisters from Ohio inherited one of the rare dimes after their brother’s recent death, Russell told AP News, after the coin had been hidden in a bank vault for more than 40 years.

The sisters, who wish to remain anonymous, say their brother and mother bought the coin in 1978 for $18,200, equivalent to about $90,000 today.

Their parents, who owned a dairy farm, saw the currency as a financial safety net, they told Russell.

The coin is now on display at a coin show in Tampa, Florida, before the online auction in California closes in late October.

While there’s a chance more examples of the rare dime exist, they would only be found in 1975 “proof” sets, and not in your change, experts say

While there is a chance that more examples of the rare dime exist, they will only be found in the 1975 “proof” sets, said Ian Russell, president of GreatCollections

The bidding rose to $280,000 on Thursday, September 12, with 45 days left to go.

But for those hoping to find a rare coin in their change, Russell has bad news.

There is a chance that more examples of this rare dime exist, but they can only be found in the 1975 “proof” sets.

“If you have old proof sets at home, your grandfather or father may have ordered them and forgotten about them. If you have a 1975, look at the dime,” Russell said.

Last year, Russell revealed to DailyMail.com the most valuable items he has ever sold at auction, including a silver dollar worth $12 million and a set of Lincoln pennies that fetched $7.7 million.

He developed an interest in rare currencies in his teens and today he typically sells around 5,000 coins a week.
