Learn How to Recognize a Reverse Proof Coin

Definition Of a Reverse Proof Coin

A reverse proof coin is a coin that is struck in the same manner as a normal proof coin, except that the fields are frosty and the raised devices are mirror-like. The term “ reverse proof ” does not mean that entirely the reversion side of the coin is struck in the Proof eat up. The stallion mint is in proof finish, with the term “ inverse ” stemming from the fact that the fields are frosted preferably than the devices .

Although other mints from around the earth have been making reverse proof coins for a phone number of years, the United States Mint produced its first reverse validation coin in 2006. The mint commemorated the twentieth anniversary of the Bullion Coinage Program by issuing a particular american Silver Eagle bullion mint minted in Philadelphia and an american Gold Eagle minted at West Point. Both coins featured the reverse proof finish.

Since that time, a number of other coins have besides been made with the reverse proof finish up, including ( but not limited to ) the stick to :

  • 2006-W American Eagle Gold $50 
  • 2006-P American Eagle Silver Dollar 
  • 2011-P American Eagle Silver Dollar 
  • 2012-S American Eagle Silver Dollar 
  • 2013-W American Eagle Silver Dollar 
  • 2013-W Gold Buffalo (Bison) $50 
  • 2014-W Kennedy Half-Dollar Silver
  • 2015-P Roosevelt Dime Silver
  • 2015-P Presidential Dollar Harry S. Truman
  • 2015-P Presidential Dollar Dwight D. Eisenhower
  • 2015-P Presidential dollar John F. Kennedy
  • 2015-P Presidential Dollar Lyndon B. Johnson
  • 2018-S Lincoln Penny 
  • 2018-S Jefferson Nickel 
  • 2018-S Roosevelt Dime Silver 90%
  • 2018-S America The Beautiful Quarter – Georgia
  • 2018-S America The Beautiful Quarter – Minnesota
  • 2018-S America The Beautiful Quarter – Wisconsin
  • 2018-S America The Beautiful Quarter – Michigan
  • 2018-S America The Beautiful Quarter – Rhode Island

Fun Fact

The reverse proof Gold and Silver Eagles are the most sought after coins of the 2006 minting year.

How proof Coins Are Made

proof coins are specially made specimen coins sold directly to collectors that showcase the mint ‘s artistic beauty. The process begins by particularly preparing the planchets for striking. This normally involves burnishing or polishing the planchets and then washing them to make sure that there are no alien objects left on a planchet surface .

The coin dies used to strike proof coins besides receive special treatment. The dies selected to make the proof coins are of the highest quality. additionally, the dies receive a treatment to impart a frost coat on the stallion assume face of the die. primitively this was done by treating the die with acid. In advanced times a computer-controlled laser imparts the frost coat on the die. Since the devices of the die are recessed, the finish process polishes the sphere open merely. When it is used to strike a coin, the field is a mirrored coat and the devices are frosted to accentuate the details.

There is some argument amongst numismatists and coin collectors as to which surface coating is preferred. More traditional coin collectors like the proof end where the devices are frosted in the fields are mirrorlike. however, newcomers to the coin collecting hobby have tended to prefer the reverse proof finish where the fields are frosted and the devices are mirrored .

The Difference between Proof Coins and Reverse Proof Coins

The manufacture process of invert proof coins is identical alike. Planchets are selected for their high gear quality, burnished/polished and then washed just like regular proof coins. It is the readiness of the coin die that makes the reverse proofread coin dramatically different than a regular proof mint .

fair like regular proofread coins, the mint die is specially selected for its high quality. alternatively of applying a frost over the stallion come on of the die, the die is polished to a eminent semblance finish. A computer-controlled laser frosting machine then scans the coat of the die to recognize the remainder between the field and the devices. Once that is complete, the machine then uses its laser to apply a frost complete alone to the recess device areas of the die. When the die is then used to strike the mint, the fields of the coin are frosted, and the devices have a mirror finish .

Before the advent of computer-controlled machinery at the United States Mint, overrule proof coins were a labor-intensive manual serve. Since it was impossible to polish entirely the recessed devices on the coin fail, a mint proletarian would have to apply a protective coat to the recessed areas so the acid would lone etch the plain areas of the mint die. This is the chief cause why they were very few reversed proof coins produced before the second coming of computer-controlled technology .
