Here is a Guatemala Real “cob” I bought recently on the cheap. I bought it because I thought I could tell what the date is. Whether you think that’s a worthy endeavor from a collecting standpoint or not is a different question. 😂
What do you think the date is? What rationale did you use to arrive at your conclusion?
It’s fun! Eventually I’ll probably submit it to see if I can convince PCGS of my belief.

Based on the curved shape of the third digit I would eliminate 1, 4, 5 & 7.
Then I'd consider what are rounded at the top, 2, 3, 6, 8 & 9
Then knowing that cobs at Guatemala run from 1733 thru 1753, to the best of my knowledge, I would then eliminate the 2, 6, 8, & 9. That would leave only the 3. So now I am assuming 173X.
The last digit also seems like it could be rounded at the top, though perhaps a little differently than the second digit, so I'd eliminate the 1, 4, 5 & 7 again.
The little notch on the right side at about two o'clock makes me want to guess 6.
So, without going to the acsearch, I'd guess 1736.

Looks like 1743 or 1747 to me. Can see the tops of 4 and flat top of either 3 or 7, then rosette after the date, then G of the mintmark (the notched blob)
I think you’re looking at the wrong part. The “notched” digit you refer to is a G for Guatemala. Left of that is a rosette. Left of the rosette is the last digit of the date, which has a flat top.
I agree with you @TwoKopeiki on all counts. Furthermore I believe it’s a 1743, when comparing images of known 1743 vs 1747. You’ll notice the giant center dot just below the crown, which tends to show up on the 1743 with that size and position. Also, the spacing and size of the rosettes in relation to the date and “G.” The1743 has large rosettes crammed together. The 1747 has small rosettes spaced far apart. Here are a bunch of comparables. I think it looks like a 1743. Anyone agree or disagree?

Wow! Someone sure likes cobs. Yes, the OP coin is 43.
Proximity of the G mintmark to the pillar, size of rosette, and and spacing/orientation of the elements matches the 1743 G J 1R.
