1832 O-106 Bust Half Dollars - periodic ridges on the edge.

zrnumismatics

Hi all,
These were part of a large collection that I've been purchasing within the last year.
They are both high grades and both O-106 unless I am mistaken. There are grooves covering the lettering periodically on the edge of both coins. The lettering is not double-struck. I can't find any examples of this online. Does anyone know what causes this?

It’s an experimental edge. Doesn’t add any value but certainly an interesting piece of mint history leading up to the reeded edge coins.

My 1832 dash date has them.

Interesting, had not heard of. I looked at my 2 1832's but they are in a slab so can only see a little over half the edge. The 103 I am not seeing any. One area I can kind of 'imagine' them. The 110 has them in multiple places and somewhat distinct.

So are these edge lines consistent for a particular variety? That is the variety either has them or not. Or can some of one variety have them and then another not?

I appreciate the help. Definitely a cool piece of bust half history.

I don’t have enough info to say for certain but several varieties in 32 have them. Not sure the percentage of each variety that has them.

Thanks, that is what I was wondering since the edge lettering does not necessarily follow the die usage. But hey now I know they exist and I even have one.
