They brought up a lot of that coal to sell so there's a good chance its real. People will try to counterfeit anything but I haven't heard of a market in fake Titanic coal. RMS Titanic Inc sold it as way to raise money for future expeditions as so the story goes.I have a piece of coal that has provenance as being from Titanic. It is just a little sliver. Who knows maybe it isn’t real, and all the paperwork is made up, but I like to believe it is.
