If anyone has a link to an article or some way of explaining the process I would be very helpful. TIA Report this Post to the Staff

SPP-Ottawa Moderator Canada 10460 Posts	Posted 05/29/2016 8:52 pm Planchets are not cut a single row at a time. There are often two rows of planchets being cut simultaneously, with the second row offset from the first row, to minimize the waste with the scissel. If you look at a sheet of scissel, and imagine a slight slippage in the strip of metal being fed, double clips are easy to envisage.

SPP-Ottawa Moderator Canada 10460 Posts	Posted 05/30/2016 11:56 am Nope... but the scissel cutting process is probably different from US coins, whereby you see most corner clips.
