In the 40 years up to 1921, over a million of them were minted. Surely the conductor could have accumulated 165 of them.

I will recalculate with whatever was available starting in 1921, if that is what you're getting at.

In circulation, not, in the conductor's pocket

coins minted thirty years earlier were almost certainly "in circulation". then you say "in 1921 currency". Are you saying the change was rendered in currency minted in 1921? We've strayed a bit from the paragraph in your book. I reckon there are multiple answers to the puzzle, I think I've offered one valid one, though perhaps not the one in your book. I'll hang on until I have an epiphany or you offer the / a different solution.
