NGC shows off new reverse proof error half dollar

Hooray for NGC for finding and photographing the new reverse proof 2018-S half dollar error coin.

Here it is with a normal reverse proof.

Notice how white the field is of the normal reverse proof half dollar.

A reader previously had notified me of its existence.

I wrote about it Aug. 8.

Unfortunately, the image the reader had provided was very bad.

Now we have a good one thanks to the professional capabilities of Numismatic Guaranty Corporation.

NGC calls it the light finish reverse proof.

“This variety results from an obverse die that was not properly prepared, imparting a significantly lower contrast finish on the coin’s fields as compared to the white fields typically seen on reverse proof coins,” NGC said.

“NGC has graded more than 9,000 silver reverse proof set half dollars as of Aug. 31, 2018. Fewer than 10 percent of these have been attributed ‘light finish.’”

Not only have we got a great image, we already have a population estimate.

Ten percent of 9,000 is 900. Search your sets.

“The U.S. Mint is a highly sophisticated operation, so it is always fascinating when varieties such as these occur,” said NGC President and Finalizer Rick Montgomery.

“This is just another example of how dynamic the world of modern coins is,” Montgomery added.

As to how this error coin came to be, NGC provides the explanation.

“To create the reverse proof finish, the U.S. Mint polishes the die’s design elements and vapor blasts the fields.

“This imparts a highly reflective finish on the coin’s design elements and a matte finish on the fields, which is the opposite of the ultra cameo contrast typically seen on proof coins.

“This variety appears to have been caused when the U.S. Mint did not vapor blast one or more of the obverse dies.”

NGC quite rightly toots its horn in making the announcement of the find.

The firm said it attributes major varieties through its VarietyPlus® attribution service by request for an additional $15 fee.

The 2018-S reverse proof set went on sale July 23.

Its 200,000 mintage did not sell out right away.

Did the find of the error half dollar help motivate buyers to push the set to sellout status by Aug. 22?

It certainly couldn’t have hurt.
