Many error collectors and dealers alike are unaware of the Dual dated Double denomination error.. That's how very rare they are. With only approx. 20 known examples known for all combined dates & denominations, it includes any Double denomination error with TWO different dates. Such as a 1999 Cent struck over a struck 1998 Dime..

    These can only logically happen when at the end of one coining year & the beginning of another. A previously struck dime (1998) gets stuck in a Mints hopper Trap door and then the hopper is filled with planchets destined to be struck by the upcoming new year dies (1999). So it appears this rare combination of errors can only happen at the years end and if all the error circumstances are right and lucky enough to happen!

    With only approx. 20 known for all dates & denominations for dual dated specimens. Normal double denomination errors with the "same" date, number approx 900-1200 known. That's a 45 to 60 to ONE "1" ratio.. Same date Double denominations currently costing $800-1,100. you do the math! 60 x $1,000. Hmmm! sound like todays prices of $6,000-10,000 are pretty cheap.. Lots of room for growth here, especially in the direction the error market has been heading, UP!

    But you say! there's 20 known? Look at all the known "U.S.Mule" errors, 10-12 known? That cost $75,000-125,000 each, Look at any regular or error coin with a Population of just 20..
