Just my 2 cents worth, the coin is a problem coin there are enough graded examples available through the more reputable online auction houses that pop up more frequently than expected. Have owned the 1875 P 75 CC 75 S and 76 both in details and original condition. In my experience selling details graded doubledimes bring about 55% value of a non details example they were coins I shouldn't have bought and regretted it the original examples brought a nice premium. For a good looking XF - AU example expect to pay a premium over price guidelines there's enough of them out there where every 3-4 months they come up. Rare scarce etc. but enough survive to meet demand I was buying these at 4-5 hundred bucks back in 2018 they have appre iated nicely. Check out the populations report on the sleeper 1876 business strike, better coin i.m.o. than the 75 CC just not as hyped.
