When initially doing this work I had no focus on naming things for others as I had no intention of the stuff going into print.

Yes, doing a version of a coins across using my aesthetic (which by the way is the way I DID think about it) using dissimilar coins was a no-brainer given access to the c/s/b gaff. The idea of two traveling and then changing places with the one remaining occurred to me much later - relatively recently in fact. Using my EG2EG to go 2for1 was shared back in late 1982 (so that handles an IPV date for the c/s/b trick) but mingling the coins across and the transposition effects was not on my agenda back then. Remember, I was going for the "ghost story" approach or what Alice saw on the shop shelves in the Wool and Water episode .

I received the Lassen set and the Van Dokkum set and sold them both almost immediately. Both sets talked way too much and the Dokkum set was too thick as mentioned above. The Johnson sets that I own put them both to shame in my honest opinion. Especially the 2 Copper 1 Silver set which I've found to be the finest to date.
