1982-p Copper At what point does an off-center get interesting?

[erex01]

I've seen off-center pieces at shows & online etc.. but my question is: At what point does an off-center get interesting? And I see people stating 15% off-center, 20% off center. How is that determined? I found this copper 82 and to be frank "I" haven't found one this far off, EVER. I realize it's not that far out, I've just never found one this far out.
Also, just so I understand a little, What is the term MD. Is that Mechanical Damage? I've heard of PMD for Post Mint Damage, just not sure of MD.
Thanks for your looking.

That's a nice one but I think still minimal. MD is Machine Doubling. You can find it in the glossary at the top of the Forum page.

The first thing I'd ask about that 82 cent is if the reverse is centered or not.
If one side is aligned but not the other then it's a missaligned die, if both sides are off then it's off center.

With missaligned dies, the more off it is the more it's worth but in general they aren't worth too much.
With off centers having some of the design missing would add more value, being more off center would add more value.
On off centers that are way off tend to have more value if they have a date, buyers seem less interested in no date coins.

There is a big difference between an off-center strike and a misaligned die strike. From the Glossary... there is also a photo of an Off-Center Strike in the Glossary

Off-center Strike: When a planchet isn’t centered in the striking chamber due to a loose or absent collar, the design will be offset in one direction. This offset will show equally on both sides of the coin, unlike a misaligned die strike, which will show a different amount of offset on each side of the coin.

Great info, much appreciated. I just looked and the REV is aligned perfectly, as in the rim is the same all the way around.
So I must have a mis-aligned die.
I didn't think it was really worth a lot or even anything. I just didn't know how people were determining how far off center.
Thanks for the info.

Yes, you are correct about the mis-aligned die, these are the ones we see most often. I've never found an off-center strike, but they are really cool looking!

Nice find... Do not forget we do have the Glossary but also Error Ref http://www.error-ref.com/ is another excellent source for info... It is operated by some of our members... The top left side of Error Refs page is a search box... You type in what you are looking for such as machine doubling and it takes you there... As for the percentage of off center or misaligned think of it this way - How much of the design of a normal coin is missing if you have everything from Abes chin north missing and everything from the chin south is on the north side of the obv then it would 50% misaligned or off center depending on the case... Hope that helps a little???

It's a MAD. It's a pretty common occurrence, not worth much to collectors unless some of the design is cutoff. Here's an example of a "keeper":

Very nice keeper indeed

So it's just as I suspected, their guessing. I've seen several people "ebay sellers" of course, stating their coin is 20% off center where it was no where near 20% of the coin. So it's just a linear measurement and what I sometimes hear is "locker room banter" LOL
Thanks

Just a simple measurement is all no need to guess!!!
