It's probably shorted something on the PCB.

I’m presuming that just means a change of fuse? How would I know if it has shorted something?

There is a 99% chance that the coins caused a short circuit on the circuit board of the ACM (Audio Control Module) and damaged one or more of the electrical components. 

If this is the case you should replace the ACM. Do not bother to have it repaired. It is much cheaper to buy a replacement ACM from Ebay. There are plenty available and usually for pretty low prices.

I agree the chances are it caused a short that burnt something out. but the thing that burnt out probably has no outwards signs that it burnt out and might have been something like one of those chip things with something like 16 little legs soldered to the board and measuring 0.5mm each.  even with a microscope you probably wouldn't find it any visual sign of damage.

If a friend has a focus . Ask if you can try his unit in yours before you buy one , they are cheap on ebay

Claim off your insurance and get another unit fitted, there's plenty on the internet and in car breakers.

That'd probably cost more than buying a second hand unit though. With the excess and increased premiums.

I'm surprised pound coins fit in the CD slot, would've assumed they'd be too thick!  Have found plenty in the bottom of heater boxes though, why do kids enjoy posting them though any slot they can find? :unsure:   I found one under a matrix once, someone had rammed the new matrix in so hard it cracked the HVAC box casing instead of checking for any debris in the bottom. :laugh:

If you don't ask you don't know.

Things you find when you purchase a s/h car, I feel another topic coming on!
