I see edynamicmarketing's listings from time to time as they're getting relisted. They aren't all AT, but an awful lot of them look like they are -- enough technicolor-yawn coins, with enough common characteristics, to make me think that edynamicmarketing is actually doing the cooking in-house.
3-5 I don't really have a problem being called RD from the pics. 6 seems to be pushing it but I assume that toning is light in person.
I tried but my lights are either too bright of too big, I don't know. Here's the best I could do. I put the glare right on the coin and tweaked it a lot so that it wasn't so faded, and it worked pretty well. I posted the normal ones and the ones with glare too.
This is a note to myself to mess around with polarizing filters on the camera and the light, and see if there's a way to get around the slab glare. I don't expect it will help, but it would be interesting to try. If nothing else, might pick up some crazy rainbows from stresses inside the slab.
Ok so when you say "oven", does he actually put it in an oven for baking things, or is it just a term for some chemical?
It's a chemical treatment, almost certainly, done very poorly indeed. I'd guess they're using some sort of liquid solution, or else not taking any care at all to prepare the coin's surface before they attack it.
Well, yeah. But not even taking it down to monochrome is going to make that coin look convincing. Oh, look -- now it's a Zombuck! Hmm. Now, just a little more work with levels, and... There. What a relief!
Of course not, but a lot of people wouldn't realize that it was juiced up like it was and think that was an accurate picture of it
So, here's another interesting item from the same seller: 1991-S Washington Quarter NGC PF68 Ultra Cameo Vibrant Gold & Yellow Toned Color It shows a background image of the slab, but with the coin blacked out. Doing a cert lookup on NGC, I find this: Hmm. One wonders if NGC decided the coin's condition has changed since it was slabbed... Oh, and the price guide value on NGC's page is $15.00; it's listed at $116.24. Gosh, I wonder what could motivate someone to experiment with gassing slabs?
