An overlay show that you mint mark is slightly lower and the overall shape is different. There were so many die scratch markers that look correct, but without the location and shape being the same for the RPM, the markers would mean nothing. I didn't see a match for it on the site. You might want to keep this one safe along with the images so you can ask them if they would list it when they re-open the attributed coins again. (The image of the RPM would probably be what they want to see when you contact them.)
