I found a really weird Mexican 20 centavos coin with a weird feature. It looks first like a lamination error. But in the "hole" is the incuse images from the back of another 20 centavos coin. I know, a vise job is usually responsible for incuse stuff, but the impression is only in the lamination breakage area. What is this weird looking thing?    Last pic is a closeup of the reverese just opposite the funkiness. Not too much difference from normal. The OS in MEXICANOS is a little weak compared to the other letters. The coin is slightly distorted along the edge, but not hugely so. Edited by Jays-Dad

That's very interesting! Is the coin round, without any distortion on the rim around the mark? I'm not an expert on Mexican coins or strike errors, but possibly a struck piece from another coin remained in the coining chamber, and the design transferred onto this coin. The piece later fell out, to leave this hole.  Just one idea.  Edited by DVCollector

The coin is round. The edge is slightly thicker at that point. The edge is slightly thinner at a spot right above the weird thing. However, I can see all of the reeding.
Interesting thought, a piece from another coin was in the die when this one was struck? Maybe.

Can you also post the reverse of the coin?

yes, lets hear the error experts!  Personally, I'll place my bets on a real strike error--not a vise job.  Edited by DVCollector

bump, c'mon I know there are lots of US error coin experts that are not chiming in because this is Mexican. Help a guy out here, even though it is from Mexico, this is really cool and I want to know what it is.

There is no flatness on the opposite side that would occur with a hammer job so I am inclined to agree with DVC, a fragment of another coin stuck to the obverse die and obstructed the strike of this coin. Correct term would be Brockage Strike of a Struck Coin Fragment, there is a nice pic of a Roosevelt dime on page 228 of Alan Herbert's book Official Price Guide to Mint Errors 7th Ed. Nice error |

As I said in the title, I've seen a lot of errors, but never anything like this. I know, I know, Mexican 20 Centavos....but is it worth slabbing?

Any other input? I've got two "not a vise job". The incuse lettering stops exactly at the break point. As pointed out, the reverse shows no squishing (I hate to pull out the technical terms). I will in fact put in my own biased Two Cents, definitely not a vise job. I now got three "not a vise job"'s. Anyone else got some insight? |

This coin is really striking my curiosity, please give opinions on whether it is an error, how rare is this type of error, is it "worth" anything, and should I authenticate something like this?

It's a brockage from a struck fragment.
