Overlapping reeds?

Is this overlapping reeding?
I've got a 1900-O with reeds shown below, it doesn't match VAM-50 (date, markers or reeding).

Here's a sequence of 12 photos, starting at 6 o'clock, rotating the coin counter clockwise.

I'm not seeing any overlapping reeds in any of those pics. They are a bit dark though.. Once you see an OR patch in-hand it's an "ah ha" moment and you they're typically easy to tell going forward. Forget about inside the recessed areas, it's the raised parts of the reeds that gets all funky and choppy looking while the recessed areas constrict in size.

My 1884 O VAM 21A shows definitive overlapping reeding. The width of the reeding is narrow, often double
stacked in succession in four to seven repetitive runs. Take a look at the page photos for the 1884 O VAM
21A for an illustration. I cannot see overlapped reeding on your photos. Hope this helps your analysis.

Heres a crude thing I just did with a pic I had on hand. Hope this helps you to visualize how to spot an O.R. patch until you can get one in-hand. The thicker blue lines to the sides are indicating the normal reeds while the thinner blue lines indicate the overlap area...

Thanks Guys! Yeah, I was looking in the recessed areas. The extra ridge in the middle area of the recess is so strong and pronounced I think it reminded my of the left photo in Roger's 84O v21A. But I can see how the ridge in the middle is taller there, and modulates/shifts in position.

Chris - your photo with markups clearly illustrates the varying width of the top of the reeding. Extremely helpful!

Between the two examples, I think I finally got it now.

Thanks again - really appreciate the help!

By the date on the OP's coin, the New Orleans Mint should have been using only a drift tool to cut reeds into the edge collar. It is nearly impossible to get overlapping reeds on part of a collar using this tool. (See From Mine to Mint for details on how reeding was made.)

New Orleans Mint requested a new collar from Philadelphia in May/June 1900. See NNP RG104 E-235 Vols 115 and 116.

Thanks for the references RogerB! I do have that book, and am even more interested in reading about reeding now 8-). Will check it out today.

Just finished a refresher on flutes and denticles rolling right into reeding. Understanding all the details around the tools and methods used to create the collar dies over the years explains a lot. I'll be paying more attention to those little 5 mil ridges in the future.

Thanks for the tip Roger. And thanks for the great book! (The searchable PDF is so helpful too.)
