1819/8 Half Dollar Overdates, are they all overdates

kevinj

Working on a book on all overdates for all U.S. coin series

For the 1819 Capped Bust Half Dollars, there is
1 1819/8 Small 9 that I believe is a valid overdate
There are 4 1819/8 Large 9 that I believe are not overdates
Curious if anyone examined these and what they think
Will update this with a PDF showing close ups in a few days, also intend to do overlays with the 8 from the 1818 Large and Small 8. Most of these Large 9 varieties have a simple metal connection between the knob and middle of the 9 that can be easily
attributed to a die scratch or crack between two design elements that are close and will crack under pressure quicker
than design elements farther away.

Thanks
Kevin

To get it started here is a previous thread on the 1819/8.

Here's a thread I made a few years ago with a quick look at 46 overdates that sold for over $100k, across all denominations.
This value filter was just one way to select a limited list of overdate coins.
