Lake Toplitz and those British five pound notes - perfect counterfeit notes.

I was thinking the same thing. Ever see the British TV series Private Schultz? It was a humorous account of the forging of £5 notes by the Germans in WWII.

Yes, I did see that series. Remember the scene where the officers stuffed their trousers with packets of the notes and could hardly walk back to their staff car?

A flashback to Sandy Berger at the National Archives.

"Operation Bernhard" had many facets - printing, codebreaking for the serial numbers, paper/inks, ... and also had several objectives: (a) buy materials from neutral countries like Switzerland, (b) pay the various spy networks, and (c) destabilize the Bank of England's currency.

These notes caused the British to re-design their currency en masse - hence the use of color on their notes.
