Systemic bias

Notice: this article reads like the world has only one country. --Smithfarm 15:02, 20 April 2006 (UTC)[reply]

No systematic bias exists here; those with information about a particular subject have shared their knowledge, and any from other countries are free to do the same. Unless those with information about poof coinage in other countries come forward, it will be difficult to obtain that information (if proof coins are even produced in other countries) Nicholas SL Smith^chatter 04:05, 4 May 2008 (UTC)[reply]

Photo of "proof" quarter is bogus

The photo of the reverse of a Washington quarter (click on 01/02/07 photo of Lincoln cent, then on "proof" in text--sorry, I'm new here and not at all savvy about how to do this post) is NOT the photo of a proof coin. I believe it is a photo of a badly worn quarter either plated or dipped in mercury. Compare the feather detail to a fresh 68.53.113.45 08:44, 2 January 2007 (UTC)quarter from your pocket.[reply]

This isn't necessarily true. Some proof quarters of the 1950s and '60s have less detail than would be expected on a proof coin. I don't know why that happens, but I've seen it. The modern quarters have designs adjusted to show more small detail, so that business strikes of 1998, for instance, can actually have a more detailed strike than proof coins of the 1960s. Perhaps someone with a little more experience with U.S. proof coins can explain how that could be. RHM22 (talk) 11:30, 4 May 2010 (UTC)[reply]

In the last several decades, we've gotten spoiled regarding cameo on coins. That quarter is a proof coin; non-cameo proofs before the 1970s are common. As the die was used, the frost effect became less pronounced over time. The main reason is a change in the way proof dies were prepared; previously, they were "pickled" in a solution of nitric acid and alcohol, which gave the light and non-durable frost seen on earlier coins. Modern dies are sandblasted, and the fields highly polished and then chromed, with the result being that virtually every coin that comes off the press exhibits strong cameo. I should think a proof coin after 1977 without frost would be fairly uncommon. The Rev (talk) 16:18, 25 June 2010 (UTC)[reply]

History of proofs?

The article says that the United States stopped producing proof coinage in 1916 but then doesn't say why, or how long or how many were produced before 1916. In fact, the article doesn't delve into the history of proof coinage at all. Thats why I read the article and I was very disappointed to find no info at all about the history. Could someone please add that in? Jimindc (talk) 20:45, 7 July 2011 (UTC)[reply]
