Can Anyone Tell Me What Happened To This 2001-P Dime?error?

Normal weight of a clad dime is 2.27 grams, this is within tolerance of wear. It looks like it got brushed with lacquer.

With that weight, there is zero chance it is missing both clad layers. I have a dime missing the reverse clad and it weighs 1.9 grams so a copper core would only weigh about 1.5 grams.

Edit: Most likely cause for the color is environmental exposure, which can sometimes give clad coinage a copperish color. I suspect the lines are attributable to the rollers used to set the metal stock to the proper thickness, more frequently seen on copper LMCs but also sometimes seen on clad coinage too.

Oops, I missed the part where you cut the surface, that should rule out environmental exposure as that would expose the CuNi cladding.

The streaky surface is often indicative of a genuine error. It's most likely that this is an improper annealing error. However, since you detect no nickel-colored metal beneath the surface, it may be more than that. It may be a true off-metal error. There are rare circumstances in which you can get a pure copper dime of normal (or nearly normal) weight. If the two clad strips run out in the bonding mill, the end of the strip, composed of pure copper, will be rolled to full thickness. It could also be an "orphan" off-metal error.

UPDATE:I was able to look at the coin with a lighted microscope,the area on the rim that I previously scratched does show a silvery tone under the copper color.I guess I couldn't pick it up with a regular jewelers loupe because of lighting,and the fact that the coin is so dark in color-much darker than the pictures posted here.

The raised areas you talk about are die chips or cracks. A Cud is a large break in the die that contacts the rim (part of the die has chipped away from the edge in that case). That sort of die damage around the nose and eyebrow is exceedingly common on Roosevelt dimes.

Ok so I just got back from my local(50 miles away)coin dealer (whom I do not really like or trust),and this is what he had to say:
1-coin was struck on a split planchette
2-improper annealing (something about copper dust baked on)?
3-coin has 4 die chips on the obverse
He also made me an offer on the coin,I will post the offer later for those who are interested.
Now,based on this information(if it's correct),I was hoping some of you collectors/experts out there would be able to give me a ball-park figure of what this coin would be worth?

#1 is incorrect, the term "split planchet" typically only applies to alloy coins that split due to an internal flaw in the alloy. Rough striations will be present and the coin will be lighter than normal. With clad coins, the outer layers can separate due to incomplete bonding but based upon the weight, it is definitely not missing the clad layers either.

#2 is difficult to authenticate without original mint luster present which would definitively rule out post-mint alteration/environmental exposure.

#3 die chips are present but they are very common and an acceptable part of the minting process so they do not add any value.


If the coin does indeed have mint luster(does not show in photos), then #2 is the best possibility since you have now confirmed that you can see nickel under the coppery color.
