and an overall picture/map of the positioning of the diagnostics & direction of change in design: The movement of the die or the coin during the pressing would NOT have caused this.

Sandon & J P M: The "Type 2" variety has thinner letters and a sharper strike. How does die deterioration or machine doubling cause that? And on the "Type 2 over Type 1" DDR variety - how does die deterioration cause this type of doubling? Look how sharp the lines are on the thinner letters: the "A" in "STATES", the “P” in "PLURIBUS", and the "A" in "QUARTER". And how do you get a double peak from die deterioration or machine doubling? I know what machine doubling is. It has a step-like or shelf-like look to it. The edge is sharp, not rounded. The doubling is thin, usually less than a millimeter. And the doubling occurs on one side of the design – this is due to the movement of the planchet in relation to the die during the pressing. Look at the thickness of the doubling on this. The edges are rounded. And look at the direction of the change in the design, especially inside the "A" in "STATES" and around the bottom of the legs in the "R" in "AMERICA". Here are some close-ups. The doubling is very prominent.

cladking, here are photos of the "Q" on both the Type 1 and Type 2. While cropping these photos, I noticed differences in the distance between the leaves to the "Q" and the the "U" and circled these.

On the second coin, I’m referring to it as a "Type 2 over Type 1" DDR variety. The second set of photos below show the doubling on the actual coin. On the word "STATES", the doubling is most noticeable in the letters "A", "E" and the "S" while both “T”s have minor doubling which is seen on both sides of the trunk. On the words " E PLURIBUS UNUM", the doubling is most noticeable in the letter “P” and the letter "L". On the word "AMERICA", the doubling is most noticeable in the letters "M", "E" and the "R". On the word "UNITED", the doubling is most noticeable in the letter "N" and the letter “U”. And on the word "QUARTER" at the bottom, the letter "A" has a double peak. There is a noticeable amount of what looks to be die wear, especially below the "E" in "AMERICA" and the “U” in "UNITED". This could be a hint as to why a proof working hub was used. On this DDR, my theory is that since this doubling has 2 different designs, the same proof working anvil hub used to create the "Type 2" variety was used on a second pressing on a working die that already had the "Type 1" design on it, probably because the "Type 1" hub was worn out and causing the edges of these letters to be ragged. I certainly would like to hear your theories on what possibly happened that caused these 2 varieties. Regards

Hello Everyone, So I think I discovered 2 new varieties for the 1983 D Washington Quarter. I think that both coins are undiscovered varieties for this year. The first one is what is typically considered a "Type 2" variety. It has thinner letters or typeface on the reverse of the coin. This typeface is very similar to the typeface of the proof design of that same year. The second one is a Doubled Die Reverse / DDR which I’m thinking is both an error and a variety. I've heard of the use (or rather re-use) by the Mint of proof dies/hubs for business or circulating coins. It is known that the Mint has, in the past, re-used proof dies/hubs for business or circulating coins to "get more mileage" out of them. In particular, this occurred with the re-use of the reverse or "anvil" die/hub which supposedly undergoes more pressure/wear than the hammer die. The TYPE B Proof Reverse Washington Quarters of 1956-1964 is an example of use by the Mint of proof dies/hubs. This has also occurred on the 1972 Eisenhower Dollars which resulted in the "Type 2" variety. In the photos below, I show the differences in these two typefaces or designs. On the word "STATES", the differences in the design are noticeable in the letters "A", “T”, "E" and the "S". All 4 are thinner. On the words "E PLURIBUS UNUM", the differences in the design are noticeable in all 3 words. All 3 are thinner. The difference is most noticeable in "PLURIB" and "UNU". On the word "AMERICA", the letter "M" does not have serifs on its ‘feet’, the letter "E" is thinner and the letter "R" has a thinner right leg. On the word "UNITED", the differences in the design are noticeable in the letters "N" and the "T". The "N" has a thinner diagonal line and has a higher ‘armpit’ while the "T" has a thinner trunk. I’m guessing that a proof working anvil hub was re-used to create business strike working dies?
