Quite a lot of them have been found in NJ. I haven't found any myself, but I do know a couple of people who have [each] found a number of them. I don't know the exact locations [where the Reale's were found] but the southern shore is a general idea. It seems the most opportune time is immediately after a major storm - either stuff is washed ashore from ship wrecks off the beach, or the beach is depleted and pockets of heavier items are exposed for a short period of time.
Given the extent of use here in NJ, I would suspect that old high-traffic areas inland would be a potential source as well. Think of really old Inns, bars, and gathering spots - any place where people would have congregated and money would've been spent (and potentially dropped). Other possibilities [in my mind] would be street tear-outs in some of the really old towns - preferably in the old "down town" areas. In some areas of NJ there were old toll roads (private) that ran the same area that are now modern roads. Find a road tear-out near where the tolls were collected and I suspect that might be a good opportunity as well.
There are still a lot of houses still in use that were built prior to the Revolutionary War. Some of those houses used to serve other purposes (beside being a home) - including bars, Inns, stores, etc.. If you can find one that hasn't had a lot of soil removed/added and get permission to hunt the property - I would suspect there is a good opportunity to find a Reale there.
Old Fairgrounds are another excellent possibility. In most cases the fairgrounds have changed over time - moving from one location to another. (In my local area the fairgrounds have changed - 5 different locations from the late 1600's to the current location).
Best of luck.....
