Donating Your Old Tram Tokens ?

Among the Roosevelt Island items that makes the rounds over at eBay are the old Tram tokens that were used prior to the Tram being connected to the MTA MetroCard system. I wonder how many of these old token are still in drawers across the Island.

If we set up one of those large water cooler bottles at the Visitor's Center once they re-open how many could we collect? Would be an interesting display. Perhaps then the Historical Society could sell them for $5 a token to the tourists.
