i just ordered this and will let you know how it turns out.
i confirmed that this part has a 2" diameter which is more than enough since a morgan is only 1 1/2" or so or 38.1mm as the books state.
i'd love to find a mirror of this shape and size as it wouldn't scratch as easily. i'm presuming this flashlight thing will scratch easily.
if this part works out sufficiently, feel free to purchase from another seller or source. i don't know whom this person is fyi.

The late Russ Logan, author of the early dime and half dime book, mentor, numismatist extraordinaire, and talented mechanical engineer, developed an edge mirror which he manufactured at his Cleveland engineering firm. He made different sizes for the different diameters of the early Federal coins, each with a highly polished mirror surface. Even when he was alive and still manufacturing them, they were sometimes difficult to find, and now that Russ is no longer with us, and they are no longer being made, the few surviving examples are tightly held by appreciative collectors of the series. Unless or until someone begins manufacturing them again, we will have to make do with the flashlight reflectors.
pretty sure it is large enough for early dollars and ikes.
morgan 38.1mm 1.5"
ike 38.1 1.5" - thought they were larger than a morgan. go figure
early dollar 40mm 1.57"
50.8mm = 2" which this should be
so this should accommodate most anything cept pan pacs or some medals perhaps

I tried it with the Presidential Dollars (using a reflector from my own flashlight) and it didn't turn out too well.

I don't wonder why some would ask why so much attention would be paid to the edge reeds. The edge, or 'third die' as it is often referred to, is often ignored. But for die marriage and 'variety' collectors, the edge, particularly of lettered and reeded edge coins, can provide much interesting and useful information. When the half dime reference was being written, and research was being conducted to determine the emission sequence, or order of manufacture, of the various die marriages and remarriages, many of the sequences were found to be indeterminate using only the obverse and reverse die deterioration. Then, primarily through the dedicated research of the late Mark Smith, it was found that the answers were to be found from the collars, or 'third dies'. By comparing the reed counts and die deterioration of the collars, and combining that with similar information for the obverse and reverse dies, a much clearer picture of the emission sequence emerged. Also, reed counts can be most useful in determining the authenticity of some coins which may have had a mint mark removed. For instance, many Civil War era Philadelphia half dimes are considerably more scarce, and thus more valuable, than their San Francisco counterparts. These two mints often used collars with different reed counts, making the mint of origin easier to determine. Perhaps not of much interest to many, but of great interest to some.

the people whom don't understand, which is fine, and the people thinking it is a waste of time fail to see a much bigger picture.
i could go on for a while about the benefits of having images of edges and i may start a thread with images for just that purpose.
we are a ways out on that probably.
my final statement until i get the reflector, "creativity leads the way"
.
here are the preliminary results. some work left to be done but a nice start.
the bottom of the reflector is angled and i'm not up for cutting it right now so it is sitting in the cardboard center of a paper towel roll. tp also will work.
the biggest challenge seems to be getting the coin as level as possible so all reeds are focused and the focal plane/working distance.
auto focus wants to get the top of coin while the focus needs to be a little further down. this is probably an ideal project for focus stacking
lighting is no problem.
i don't know these sellers but here are some people selling them on the bay if you wanna give it a try

ok
here is a much better focused example and a little larger and with an accurate count

between that and all the hot air we let out, i think we have found the cause for global warming.
for those that don't know, methane is a supposed leading cause.

just some more i tinkered with
i need to start getting the "key dates" for the top 15 most counterfeited dates and see what we can turn up. be interesting at least.
Excellent work LanceNewmanOCC!
<< <i>If this becomes more widespread, counterfeiters will also have to count reeds
i hope so. i'm for nearly anything that has to make them spend more money, effort and time.
i usually say criminals work 2x as hard for 1/2 as much but if i have anything to say about it, i'd like to change it to 10x.
the biggest challenge we have is simply getting the info to our collectors/dealers before they get burned. from what i can tell it is a matter of when, not if.

yw. one of the easiest projects i've taken on to-date. just a bit time-consuming but any hooplehead can do it.
.
this doesn't qualify as reed counting but it sure looks neat to me!
pos a over pos b or if you prefer, pos b over pos a
this one looks a little better i think.
now, lets do a pos b over pos b
I am intrigued.

oh ya. i have several more tricks up my sleeve but we won't get there for some time. everything is a process.

Hoard the keys.
In other words, way cool!
OLD THREAD i wonder how far you all have taken such methods?
While I do not often use it, I do keep a flashlight reflector for just this purpose. I did learn from @MrHalfDime's post and your posted pictures as well. Cheers, RickO
I missed this the first time around...cool stuff!
