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

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.
