@gsimonel this is a brilliant breakthrough and you are to be commended for pioneering this. Previously I was using the much more expensive LDWS “Looking Down While Shopping” technique. Particularly in local coin stores. Using this technique close to the junk drawer of a local coin dealer netted me this beautiful coin from Metapontion... Of course I had to pay well over $1 to the owner for the right to take the coin so your method is obviously superior. I look forward to the future publication with full details worked out.
