Dear Mrs Young,
the first thing to do is to photograph and identify them. Are they are is sets, still in the boxes or just individual, put into a draw?
If you put photos on here, there may be some interest from the members in buying them. Alternatively, there are also auctions that specialise in this type of thing.
I noticed you first posted this in March, ( Newbie section ) and there are now many more figures than previously thought.
( originally 2000+ ) I presume it is only the painted figures that are in the cabinet.
