I have noticed that a lot of old 10p coins are noticeably a lot thinner (presumably worn down rather than starting out thinner)

Prior to about 2010, 5p and 10p coins really were thinner. They were changed from copper/nickel alloy (Cupronickel) to nickel-plated steel to reduce costs. But in order to maintain the same weight, the coins had to be made thicker.

Oh shit! That's why they sometimes don't fit 5 to a section in my coin holder. I thought it was just poor quality control on the 5p coins.
