I think I am learning a bit with the sending of the pictures hope this better. I thought planchet/grease stamped- notice the raised bubbles are inside of the monuments pillars. Very sorry for the second post on a few of these as I was asked to make the pictures bigger, please let me know if I got it????? Thank you all this is awesome been going through my coin collection from my grandfather as well with a whole roll of mercury dimes and barber dimes (he passed long ago). I had back surgery and this has been the best therapy for me and my family.
