For what it's worth, I attend what is advertised as the "largest railway collectible show in the country". From what I have seen over the last two years, lantern prices have skyrocketed at collectors meets to the point where, by comparison, there are some genuine bargains to be had on Ebay. I would guess that for a standard, mass produced NYC lantern in decent shape, marked with the road name on either the globe or lantern itself, that you are looking at @ $120 + at a show. You probably will do better on Ebay, and better still from a non-railroad "flea market" if you can find one.
