whats it worth??

So this is very general.....and most likely hard to answer....but me and a buddy I scrap with found what seems to be a goldmine.......you know the huge industrial dumpsters?? Well, we found one...that is filled with old water heaters......I'd say about thirty of them.....and w'eve gotten connections in this area before,and apparently they have been sitting there for a year or more, my question is, what about would the value be on 30 water heaters?? Oddly enough with all the scrapping I've done I've never dealt with one before.

so what your telling me is I found a nice chunk of change thanks guys!
