2007-S Washington Proof Dollar Weak Edge Lettering

I'm not sure. I only have 1 and nothing to compare to. Here's some pix of how very weak it is.

That looks very odd. Proofs are struck twice, you would expect that to impress the letering very DEEPLY into the edge. And why in the world is the edge of the coin so rough? Proof coins typically have smooth polished edges, even on the reeded edge coins th surfaces down in the reeds don't look like that. And on the date it almost looks like the digits have broken off the collar die leaving areas of differing heights to create the digits.

Just a guess, but it looks like a broken collar. If the collar broke, it may not have held the coin tight enough to make a full impression on the rim. The notches I see in your picture are what lead me to believe this.

Hi Kloccwork

My 2007-S sets looks the same as yours , including the ridge where the collar was not completely closed .

very weak lettering .

That doesn't always hold true. Some one found this proof Cent in a set once. I wish I had found it!

I am not an expert, however the pictures posted, the date 2007 looks like the lower half of the 200 was doubled, especially the 2's lower half and the zero's have a deeper "horseshoe" appearance than the upper half of the zero's lighter appearance. This is normal?

Here's a close up. Looks kinda doubled but looks like whatever makes the lettering was jumping around and etching everything

The information on Potters site just relates to business strike coins which use a different system to apply the edge lettering. (Also the large and small font edge lettering appears to simply be new and worn edge dies.)

I am still at a loss on these proof edges. I still see no reason for the extremely rough surfaces, and I also still think it almost looks like the lettering has broken off the edge dies. (The notches where the edge dies come together is normal and should be there.)
