I am a sucker for cool historical items. While looking on ebay, I came across some pieces of coal that are claimed to have been recovered by RMS Titanic, Inc. (the company that was allowed to salvage relics from the wreck). They supposedly come from the 1994 mission and come with a Certificate of Authenticity. I would love to have one if there was a way to tell of their authenticity or not. Anyone know if they can be real? Or how to tell the fakes from the real ones?
