Re: counterfeit pound coins
"The old-old 10Fr piece in France in the 80s/early 90s"
Likewise the old 1DM in Germany (worth about 26p) was the same size and weight as the old shilling when still in circulation as a 5p coin. Many of us took a small coin bag along with us on school exchange visits for the vending machines and pinballs.
Not as good as your 2p/10Fr deal though, but then we didn't get caught :-)
