After a long and eventless drought of no finds, I came across this dime. On the obverse, the rim is suspiciously well worn compared to another 1985-D that I had at the time. On the reverse, the rim was not as worn as the obverse because I still saw a raised rim. The region where “unum” was in was selectively worn, meaning that it was worn in the particular space but not the rest of the coin. If the coin was authentically worn, the details of the entire coin would be gone. I don’t want to assume this is an error but I’ll need a hand on this. Obverse Reverse
Well lets see, the word 'Dime and unum show a weak strike, right behind the head of Roosevelt (the fattest part on the obverse). I think it is possible that during the strike most of the metal was used up forming the obverse device. I wonder if this coin is under weight and there was not enough over all to fill both obverse and reverse. I do think that the wear pattern on the obverse rim was deliberate (sanded off somehow)
A poorly struck 1980s dime. Typical for the decade, and 1984 and 1985 are quite difficult to find well struck.
Here is the 1985-D dime (right) next to a 2000-P dime (left) with the rim facing up to confirm your answers
Interesting,can you weigh it?if so looks quite a bit thicker than usual aka thick planchet,should be around (2.27 grams).
Huh! I would think that your 85-D coin would be the thinner one since the obverse rim is all worn down. What does that coin weigh?
For some reason that is rather common on 1985 dimes. I don't know if it was a striking issue or if something was going wrong with the upsetting of the rims on the planchet. If the rims weren't properly upset on the planchet you could get that kind of an effect in the strike.
I thought that it looked like a dryer coin. Coins caught edge wise in a clothes dryer exhibit a similar wear pattern.
I believe if @Yokozuna is the same person from "the other forum", then they have one of these 1985Ds also. this guy on ebay has one anacs graded and they called it "weakly struck" on the slab. Nice pictures though! https://www.ebay.com/itm/164824832461 improperly upset rim prestrike,,,, low pressure strike,,,,, trial strike,,, I don't know but it's not a "one off", at this point they all have striking similarites to each other to be simply PMD. I think it's got to be a manufacture issue of some sort, maybe a failing press....
https://www.error-ref.com/weak_strikesinsufficientrampressure/ common minor error. Unless it extremely severe, it's kind of detrimental to the desirability since there aren't too many people fighting over weakly struck coins. For example, if I search "die adjustment strike" on ebay, I get 61 listings at a wide variety of prices. When I go to the sold listing there are 4 sales all below $20.
