Anyone know of a double struck in collar coin with 2 different dates?

i have a few double struck in collar coins of the same date. i also own a few double denomination errors with different dates...
but as far as I know I have not seen a penny struck (1999) by another pair of penny (2000) dies, anyone know if it is possible, do they exist.
would that be in sense a double denomination?

I opened the thread to post this exact coin. I have seen several double denomination coins with two different dates but the 1974 nickel linked above is the only coin I can think of which is the same denomination and two different dates.

Wouldn't it be just as likely to have the same denomination with different dates? Whatever the explanation for your double denominations would be the same for single denominations. The double struck would not be near as obvious to the casual observer though.

they have double struck in collar with the same pair of dies, with the same date.
what I am speaking of may be very similar to a double denomination coin, to be struck with a dated die, and then again by a different dated die of the same denomination....
Interesting.... is there an explanation for the double date/struck nickel? Other than

When we used to get floor tours of the Denver Mint during the ANA SUmmer Seminars I saw that they used the same hoppers for both blanks, planchets and struck coins. The hoppers had a gate at the bottom so that the hopper could be lifted up with a hoist above whatever machine was next in the process and the contents dumped in.
Sometimes blanks, planchets or struck coins got caught in the gate when the hopper was emptied. If near the end of 1973 a struck nickel got hung up in a hopper and that hopper was then filled with nickel planchets and those planchets did not get struck until after Jan. 1, 1974, you could get a 1974 nickel struck on a 1973 nickel.
On my last floor tour I looked at a row of those hoppers up against a wall, and in the fourth one I looked in I saw a planchet stuck in the gate.

I understand, but aren't most different denomination strikes also different year strikes? (making me wonder how they could have been left in planchet totes).

Most dual-denomination strikes where you can read both years show the same year. The holdover from one year to the next is the rare one.
