In uncirculated condition, a double-denomination error involving a 1963 dime should be worth about $1500. This one looks a little beat up.
I hope the OP is still following this thread. I'd recommend he send it out for authentication, and if found to be real, attribution, grading and slabbing.
The weakness of the cent strike is the only thing that bothers me. It could be from being struck with false dies, but I think it is also possible that the same weakness could come from a weakly struck genuine coin. I agree with Mike Diamond that it really needs to be seen in hand by someone who really knows errors, but I think it has a fairly good chance at being real. Those who have dismissed it as just being a vise job squeezed between two coins need some remedial review on errors.
Enough with the photos...If Mike Diamond thinks you have something then you have to determine if you want to keep it or not. In either case, take it to a dealer or dealers and get their opinions and offers and determine if you want to sell it.
Most dealers wouldn't be qualified to determine if it is real or not. As I said it needs to be examined in hand by someone that KNOWS errors, most dealers don't.
If I had it, wasn't intending on being a collector, and a dealer (expert or not) offered me a chunk of change, I'd sell it in a heartbeat.
Not sure I understand all the excitement. The laws of physics - in this case 150 tons of them - say that a random Dime getting under a Cent die is not going to retain its' original detail and original rim. And a Cent planchet won't fit into a Dime die setup, and would be broadstruck with no rim. Assuming, of course, you get past the physical impossibility of it only getting caught between a single die, because there's no die markings on the obverse. Those are some breathtaking mental leaps to be making in order to come up with a Mint origin for this.
SuperDave, minimum die clearance varies, and it would take only a slight increase in the gap to ensure greater preservation of the dime details. Many double strikes show rapid fluctuations in die clearance in both directions.
I would assume based on what the OP stated that this is silver. Therefore there should be reeding on the coin. If that is in fact true, then I think this is PMD. Reason: The liberty from the cent is in a proper position so therefore the opposite side of the obv of the cent should be way off center or look like a MAD. The reverse of the coin shows the memorial as being centered on the dime, if that were also true would not the outer edge of the cent not be visible? it would look sort of like a broadstuck coin. Its really tough to make a call based on these pictures as many have said, if the OP really thinks he has something then perhaps sending it in is his best option. Heck after looking at the pics again, I could make a case for glue. Although that would of taken some work to get the orientations correct. Jon Sullivan had several of these (real ones) for sale on his site at one point.
I see enough to indicate it deserves a close study by a knowledgeable numismatist IN PERSON. All the devises are in order and the fact that it would be a light strike with the highest portion of the dime receiving the strongest image combined with the non-mirror imaging makes me think "die struck". Fake dies seems pretty far out but possible.
Shoot. I ALWAYS seem to forget about glue when looking at just a pic. Probably because it doesn't show well. I catch them in person though.
Superdave, better look again because there is evidence of both denominations on both obverse and reverse. (assuming you are referring to the OP coin and not another one I missed,) And the coining pressure of the cent press is only 40 tons not 150. Add to that it is striking a thinner planchet that it was set for reduces the pressure even more, plue the fact that the CuNi clad composition of the dime is harder than that of a cent planchet and you could very easily retain design and rim detail.
