Mexican 50 centavo piece. Is this a 1913/7?
« on: September 15, 2011, 11:52:55 PM »
This piece has confused me for a while. I am trying to determine if this is the 1913/7 variety of KM-445 or is it just a 1913? Something looks funny about the 3 but I'm sure there is an expert on Mexican coins out there somewhere.

Speaking of Mexican coins, I have heard there is a recent coin commemorating a Mexican Music Theater or concert hall but I sure can't find a listing for it. Does anyone have any ideas what it might be and where I could find it in SCWC? if anyone has one for sale or trade...oooooops...wrong subject.  Alan in Massachusetts

I can't enlarge the image on photobucket, so take this with a bale of salt. I think the 3 is misaligned with the rest of the date. Normally that happens when a die is prepared towards the end of the year and the engraver is not sure if it will be used in the current or the following year. The last digit is not engraved until the die is called for. As an added advantage, the last digit can be engraved by an engraver with a lesser rank/skill.

If this were an overdate, you would see parts of the seven "sticking out" below the three.

I don't seem to be able to get it any larger than the above.
It's not clear enough to tell really if it's an overdate, the best I can say it that the '3' looks odd.
So at the moment, without even bigger pictures, I agree with Peter.

If you have a terrible memory like me, you find coins with musical subjects and you think - was that coin one which Alan in Massachussetts was looking for - then you can never find any mention of it on the forum...

Just an idea but would it be worth collating all these coins you look for into one thread?
One of these days I'll find the Tongan coin - but I can never remember the details of any others you look for :)

All I can do is maginify it electronicly but that answers nothing.  Needs to be scanned at a larger resolution.

I don't know how you do that, but it's rather good.
Looks like a 3 over a 7 now :)

Let's try this one at 1200 DPI. I hope it is clearer.

For me, much depends on the black pixel in the lower part of the 3. If that's dirt, you have a post-cut date. If it is the shadow of a raised part of metal, you likely have an overdate.

Another indicator is the uppermost line of the 3. I saw it as a single line on the earlier pics. On the 1200dpi it looks like a double line. If that's just my eyes, too bad. If it is a double line, there's likely to be a 7 underneath.

Hi, Peter. It's not your eyes. There are 2 distinct lines at the top of the 3. The pixel inside the tip of the 3 is metal...not dirt...used my microscope. So you think it might be a 3/7?

I just, on a whim, looked on E-Bay and they have a 1913 50 centavo listed (the uncertified one has a clearer date) and the 3 looks quite a bit different than my coin. I am inclined to go with Peter on this...I believe it is a 1913/7...any other opinions?

alan  Thanks.

Ok here is the 1200 enlarged, sharpened and contrast enhanced. I think photobucket is limiting the image.
If you emailed it to me, I might be able to manipulate it a little and get a little better detail.

I am much inclined to call this 1913/7. The next question is how such an odd overdate came into being. I would have expected 1913/2, but the overdate is clearly not on a 2. Another possibility would have been 1913 over 1907, but the 1 is sharp and clear. A die cutter believing today is 1917 when it is 1913? Hard to imagine. Mysterious...

Another slight possibility is that it was originally a "5" and the vertical part of the 5 was moved to made it look like the slanted part of a 7.  Were there coins like this in 1915?  I don't think it likely to be altered but thought I should mention the possibility.
