Mexico 1c 1927/6 overdate

[KurtS]

Here's one the few overdates I found at the last show. This one is pretty subtle--the overdate amounts to one remaining curve where the 6 intersects the 7 top stroke. Without knowing the exact markers on this one, I wouldn't know where to look.



Compare to this coin, which one dealer attributed as an 1927/6.
I'm pretty sure this is a 1927/7. (This coin is from my collection)

You have the top one correct: 1927/6, on the first one, and the second is 1927/7.

You have the top one correct: 1927/6, on the first one, and the second is 1927/7. Nice looking coins.

Thanks! I think the 1927/7 is AU, and the 1927/6 is probably VF, unless it's just a weak strike on the eagle--hard to distinguish what is wear.

I've also wondered if Mexico was still adding dates after making the dies--or were these done by hubbing the dies with two dates? The reason I ask...is that on Mexico 20th C. overdates, only one digit seems affected. In other words--a 7/6, 1/0 etc. I never notice doubling on the remaining digits, such as the Mercury 1942/1 overdates (DDOs) or the Australia 1933/1932 below. The date position on many 20C. Mexico coins differs between coins of the same date, which would suggest they're not on the hub originally?

For example, an Australia penny overdate clearly involving two dated hubs: 1933/1932

Kurt, another nice set of pictures. In the pic of the '27/6, there is something just right of the horizontal of the 2. Any idea what that is? Just a hit? It makes me wonder whether the 6 is actually there or something else caused that.

[Dick]

garryN, I saw that, and took the image to HUGE size, on my Zoom-Tech app, and it seems to be only a hit. Imho.
Kurt, I have not had the privelige of a visit to the mint(s), in Mexico, so I can't say. I do believe thety might have used a rack. This because at one time there were 11 mints in Mwexico, and that means a huge expense to supply from one source. I think Mexico City, is the only operating mint, there, now days. I haven't seen enough of the bi-metalic coins yet, to form an opinion, but they could be a nice surprise, at some time, if my thoughts re the making of the core, and ring is correct. i believe that older coinage is being used for the core, and invariably, there will be a dual-date coin show up, eventually.
As usual, your pictures leave me with the desire to do the same, but all I get is a bad taste in my mouth,when I look at one of MINE! OPne day, I will get it right! I'm not about to give up!

Yep, I think the mark to the right of the 2 is a hit. Dick, visiting their mint sounds interesting! Thanks for the info...it just got me thinking because I notice these tiny details, such as date positions. Perhaps I'll do a comparison sometime.

[Dick]

ybe you should consider attributing....LOL

I am still not convinced by the '27/6. But its still a good reference coin in case a better example turns up.

On the other hand, the '27/7 looks like the 7 was punched three times. There is a ridge at the top of the horizontal that might be a punch.

[KurtS]

[GarryN]

I guess you are right. Its that mark right of the 2 that was distracting me.

I have a 27/6 PCGS 35. Here's a pic at 60x with my intelplay microscope.

For some reason the img isn't working for me. Can anyone tell me why?

SMED, Your image came out just fine.
I see a "shadow to the right, and above the "7", which looks like it might be a remnant of a third puunching. I hadn't noticed it before. the othet images do confirm a '27/7.
