1772 PTS Jr 8 Reales Charles III Bust

In determining the potential host I was also going to ask if all the anomalies discussed so far would have likely shown up on other genuine coins from that original date?

Also, approaching from another angle, is there anything on this coin that would be considered authentic, but also difficult to produce by a die used for forgeries?

I believe the Potosi mint mark is one of the more intricate. Also, the edge pattern is often looked to first when attempting to authenticate. Of those two areas, or any others, do you feel this coin represents them accurately? If so, would that lead us back to considering the host coin scenario? I never answered swamperbob, but the two overlaps on the edge are in fact exactly 180 degrees apart.

Also, there are a couple things that still bother be about the 7s vs some of the other anomalies.

On the second 7, why leave the extra termination on the upper bar? If someone was going out of their way to produce this date, wouldn't it have been just as easy to tool/clean that portion off?

TwoKopeiki, you originally noted the possibility of both 7s being repunched. Looking closer I think you are correct. The first 7 appears to be tilted slightly leaving excess on the upper right side of the vertical bar, and potentially creating the rounder/fatter tail. My question would then be, why repunch both 7s, especially if it was a host coin?

I think there can be a lot of speculation about all the anomalies, which I think is good, but at the same time it can tend to muddy the investigation if collectively they don't align to a theory. That brings me back to the question I raised above, what is authentic about this piece?
