It's not surprising when you consider the same company behind that Titanic piece is also responsible for promoting similar products for tragic events, such as the 9/11 disaster and the 2004 Asian Tsunami as shown in this example from the SAME company:

If they want to colorize coins or currency commemorating special events, sports figures, political figures, etc., that's one thing, but to use that means to commemorate "tragedies" is quite another. There's one listing on their web site about that 2004 Tsunami, suggesting that "a portion" of the sale of every piece will go to the American Red Cross. I just wonder how true that is and if there are records to prove their donations. Although I suppose with that wording they can advertise it even if they donate only a penny from each sale.
Anything to make a profit...but they won't profit from me, as I'd never buy such things in the first place!
