GMS5 do you know how to do and overlay. I suggest you should do one. you will see for yourself.

This coin received special assistance outside the mint ( PMD). If a smaller foreign planchet were struck in a dime chamber the metal flow would be outward on the planchet or towards the collar. The rim would not be pushed back towards the centre of the coin then flattened. |

What I find intriguing is that if the coin has been flattened, it's smaller in diameter ?

GMS5, that's not a legitimate error coin. That just an altered Canadian Dime. It's Post Strike Damage ( PSD), since it happened after it left the Canadian Mint.

Time to pull the trade ticket out. PMD. 3 dimes in 1. And one of them is an old nickel dime. Here is how I would make it. 1st dime (old nickel)- hold in a shallow collet in a lathe and face the first side off to just remove all detail. Flip coin and face 2nd side to remove all detail. Bore it out to any ID you want. You have now established the thickness, and the OD you need to make your 2 inserts. The total thickness of the inserts needs to be the same or less than the ring thickness of 1st coin. 2nd and 3rd dime (plated) - Hold in same collet as 1st coin. Do not face, ...turn... the OD to match the ID of 1st coin at least more than half of the thickness of 1st coin. Repeat for 3rd coin, but be sure to use the other side of the coin. Turn as coin 2. Change collets to fit the turned OD of coin 2 and 3. Face off original dime diameter to desired thickness.(less than half the thickness of coin 1 remember). Still with me? Ha Ha. Now you have your 3 pieces. Pressing them is tricky to keep the orientation correct. There should be a slight interference fit between parts 2 & 3 with part 1. But I have a feeling this was made size for size, and when assembled, was loose. A quick squeeze in the collet and that is why your dime is smaller in OD. You mention the ring being a different colour. I'm pretty sure its nickel because I don't see a tell tale copper ring around the inside of the reeding if the plating had of been faced. Trust me, you would see it. This is evident with the 2 inserts. Note how the copper is visible all the way around the OD of the inserts. Plating tends to tear, not cut. This was the tattered edges getting de-burred exposing more copper plating. The width of the "rim" is not a rim at all. The rim was lost in Op. 1 when faced. The rim width was set by the ID hole in 1st coin. Try a drop test on your table. Does it sound "dull" or "dead" compared to a full dime? Sorry to be so long winded, but you have a dime that is worth 30 cents (get it-3 dimes) in change, and $30.00 worth of craftsmanship. Like I said before...Very cool.....and... I had no hand in this coin. Keep it for sure. "B'eh....B'eh....B'eh...."

WOW, Thanks for all the weighing in gents. I'm now leaning towards post mint damage. Either way it's a great conversation item, and not bad for having come out of a roll at the bank. I'll keep it in a 2x2.
As for overlays, I don't know how to do them yet, but I'll research that for future use.
Thanks all.

Your second set of pics shows better as maybe a struck coin except for the funky rim on the reverse, might justify a XRF the lathe creation just seems too complicated for a dime error, there's very little material to start with

Many different ways to manufacture this depending on the equipment available and the effort you want to put into it. I simply think it's cool that you found it,why did the guy who made it, dump it? Did you try the drop test?  .

I guess a sanded rim would account for the weight loss but it's still slightly smaller. The condition of it would imply it's seen some sort of machine

i did a drop test last night and it sounded like a regular dime but light if that makes sense, it wasn't dead sounding at all.

OK, how does the reverse and obverse orientation look? Like a die rotation.

There is no rotation, it is aligned like a normal Canadian dime.
