Adam DeLacey:
Adam will look carefully at the clothes to see if they are mens or womens and what sizes.
Harry finds that the chest is empty.
The bundle of clothes are men's clothes. The man not currently wearing them would appear to be of average size (so, they won't fit Adam at all).
A coin falls out while Adam is examining them... he goes through the pockets more carefully. They contain typical personal effects that a man walking around might have-- there are more coins, which add up to almost thirty cents (an average amount for a man to be walking around with). There's nothing, though, that would suggest anything more about the identity of the man.
