I have found 2 and 1/2 magic coin trick halves in 4 years of searching. One of them was in another CRHers dump, so they apparently missed it while only edge checking. Another of them was in a handful of CWRs I know were silver-sniped by a teller at the bank. The 1/2 of one was in a Loomis MWR. It was the hollow obverse side.
