They do it at Nine Ladies too and sometimes leave messages - prayers I suppose - a bit like lighting a candle in a church.
There’s this one on the North York Moors – it has about a dozen coins pushed into its cracks. The coins can (and do) cause damage – expanding when hot and possibly causing the stone to crack.
I think Scottish healing wells are called Clootie wells where people tie things to the trees nearby:

And some trees get coins pressed into the bark like the wishing tree in Argyll. A friend of mine says he often finds coins in the hollows of standing stones (especially in the Peak District), but I've never found any. Anyone else?
Candles, t-lights, incense and fires in places like West Kennet Long Barrow are another source of damage to monuments – not to mention edible offerings and the vermin (non-human ;-) they attract.
It’s been said a thousand times here and elsewhere – Leave nothing, take only memories.
