Message:: [QUOTE="Clinker, post: 583895, member: 6229"]When we read or hear the word "Proof" those of us coin collectors who own a "Proof" coin/s or a "Proof" set/s can appreciatively envision a special coin that was multiple-struck (twice or more) by a mint using highly polished dies under tons of hydraulic pressure on highly polished blanks (planchets) resulting in the finished coin/s having brilliant shiny (mirror-like) surfaces (fields) on both sides of it like the following: Thanks to Wikimedia Commons you, who don't own a proof, can see the difference of quality between Brilliant Uncirculated coins made for general circulation and the same coins produced as "Proofs" for coin collectors by clicking this link: <a href="http://en.wikipedia.org/wiki/File:Bulgaria_1_lev_1981_commemorative_-_uncirculated_and_proof_versions.jpg" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://en.wikipedia.org/wiki/File:Bulgaria_1_lev_1981_commemorative_-_uncirculated_and_proof_versions.jpg" rel="nofollow">http://en.wikipedia.org/wiki/File:Bulgaria_1_lev_1981_commemorative_-_uncirculated_and_proof_versions.jpg</a> Here are photos of other "Proof" coins from mints around the world: A United States 2002 "Proof" Cent courtesy of Wikipedia:  <a href="http://en.wikipedia.org/wiki/File:United_States_penny,_obverse,_2002.png" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://en.wikipedia.org/wiki/File:United_States_penny,_obverse,_2002.png" rel="nofollow">http://en.wikipedia.org/wiki/File:United_States_penny,_obverse,_2002.png</a>  A Russian Copper "Proof."

Future posts will refer to the other "Proof" types previously mentioned. Long ago mints of the world found that money could be earned by providing specially produced coins (proofs) for numismatists. France was one of those countries. In the late 1800s France's Paris Mint invented a new process which they called "Matt" (American English "Matte"). Here's a photo of a French Gold 10 Francs of 1899 "Matt Proof" courtesy of Coinarchives.com: <a href="http://www.coinarchives.com/w/lotviewer.php?LotID=575426&AucID=421&Lot=2551" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.coinarchives.com/w/lotviewer.php?LotID=575426&AucID=421&Lot=2551" rel="nofollow">http://www.coinarchives.com/w/lotviewer.php?LotID=575426&AucID=421&Lot=2551</a> If you read the text accompanying the photo you saw that Britain and the United States also struck "Matt Proof" coins for collectors too, but other countries produced their own "Matt Proof" coinage. Here's a photo of a 1902 "Matt Proof" British Sovereign courtesy of coinarchives.com: <a href="http://www.coinarchives.com/w/lotviewer.php?LotID=574800&AucID=420&Lot=3223" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.coinarchives.com/w/lotviewer.php?LotID=574800&AucID=420&Lot=3223" rel="nofollow">http://www.coinarchives.com/w/lotviewer.php?LotID=574800&AucID=420&Lot=3223</a> Before I add links to photos of other "Matte Proof" coins, let me explain the process of creating a "Matte Proof." NOTE: "Matte Proof" coins were not popular with the numismatists of the era they were struck, but are a highly sought after prize in today's coin market. In the early days of "Matte Proof" coinage the blanks were sandblasted to give the planchet a grainy low-reflective surface. Latterday productions are treated with acid (some before striking, some areas of the coin are treated with acid after striking). Many U.S. "Proof" coins from 1909 through 1916 were "Matte Proof" types and, because of their low mintage figures, are now among the most sought after U.S. coins. Those U.S. "Matte Proofs" include Lincoln Cents and Gold coins. From time to time other "Matte Proofs" were produced as these two which very few collectors know exist (courtesy coinpage.com): <a href="http://www.coinpage.com/coin-image-1856.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.coinpage.com/coin-image-1856.html" rel="nofollow">http://www.coinpage.com/coin-image-1856.html</a> <a href="http://www.coinpage.com/coin-image-3445.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.coinpage.com/coin-image-3445.html" rel="nofollow">http://www.coinpage.com/coin-image-3445.html</a> The following "Matte Proof" examples from around the world were a delight to discover.
