I really like the Cent struck on already struck Dime. (Double Denomination). Can you take a close up pictures of the Cent struck on Dime? To have an idea of the host coin. For the KHD off center, how much does it weight?
Very cool errors. I'm not an error collector, so have no idea what they are worth, but many others on this forum are, so one will come along soon. Welcome to CT.
Sound? Did you drop it? And the edge of the coin isn’t enough to differentiate between 90% silver and 40% silver. This method is far too unreliable even for a trained eye.
The half dollar looks very very nice. I don't believe the cent is what it claims to be. 1st off, it appears to be larger than a dime, but that would need a comparison, stacked with other dimes/ and other pennies to see.
You can try with a tissue test with your KHD. Put the tissue over the coin and if it silver you can see through it clearly.
The edge should be able to tell a 90% from a 40% silver half. Telling a 40% for a copper nickel by the edge I have always felt is more questionable. Weight would also tell a 90% from a 40%, the tolerance ranges don't overlap (min for 90% is 12.24 grams, max for 40 % is 11.9 grams) You can't tell 40% from coppernickel by weight though, they have a large tolerance overlap. It should be larger than a dime. It starts out the size of a dime and then is struck again by the cent dies in a collar that does not restrict further diameter expansion. And from the images the coin is smaller than a cent and the rim is missing above Lincoln's head. It looks genuine to me.
The cent on dime is absolutely 100% legit. If the dime also showed the date as the cent does, it would be worth a little more. And the more overall features of both denominations show, the higher the price, as well as condition/wear. I don't see heavy details from the dime, but it is definitely visible for sure. I would need much clearer photos to help with a value. But I would say at least in the $275 range at least if it is clean and would be straight-graded. Here is one from my collection, which I have had offers for over $700, but I am not selling it. It is graded as a 65, but was told by a premier error national expert to send it to PCGS as it will likely be a 66.
I am now seeing Roosevelts face on the second cent photo. The image does not look reversed, it is good. I was going off the 1st photo before, where it just looked like zinc on the upper edge. If this cent was struck on a dime, why is it copper colored and not dime colored?
If you can get some accurate weights on both coins that will make it a lot easier to narrow down (As stated by @Conder101 and others). Also a good picture of the edges. IMO, it looks like you may have something good, but those 2 pieces of data will go along way to help determine if your O/C Half is a '64 and if the Cent on dime is legit. If you do those 2 simple things, it will make "taking in all the information" a lot easier
The double denomination is genuine, and based on photos only (not having the weight) I'd say it's a good chance that the Kennedy Half is 90% silver. Impossible to know until the weight is given.......grains or grams.
