I am wondering if anyone has cut up coins so that they are like thick ribbons. I worry that the ribbons would fall apart and I'd be left with tiny scraps. But I was thinking of doing it because I think that it would maintain the layering that the coin has, instead of rubbing it out and separating the layering. Of course, there is fold and stuff, but I haven't figured that out yet. I hope that this might be an intermediary between those two methods. (I don't think Mac Baren roll cakes would work since they aren't so tight. But escudo, navy rolls, etc. might survive.)
