I can't say that i have seen that exact same cut but I have had a lot of 50 and 100 polymer notes that have been cut almost like someone had used an exacto knife but it did not cut the bill completely through,
Many bills have had corners missing and they were to defined and straight edged to be ripped
I can only assume it is people cutting bills to satisfy their curiosity that the new polymer bills can be torn/cut or tellers using a sharp edge knife when opening bundles/bricks before placing them in the atm... which I know that the BOC has informed banks not to do...but how many people read memos
