Fossildude19 Posted July 29, 2016 Share Posted July 29, 2016 Seller claims this is 100% Natural Trilobite! If it is natural, I think it is only natural plaster, or resin! Have a look at those air bubbles. I would stay away from this one, at all costs.

CraigHyatt Posted August 2, 2016 Share Posted August 2, 2016 (edited) I'm looking for a trilobite bolo tie. It would be perfect for that. Resin should be plenty durable. ;-) P.S. but not one that will frighten small children....

tmaier Posted August 3, 2016 Share Posted August 3, 2016 We see a similar con jobs in ancient coins. An artist will spend a lot of time on a cast or die, and they are very hesitant to stop making copies, even though they are giving themselves away by making so many identical copies. If the fraud is pretty good, they try to get good prices on the first few copies, then later on will dump a lot of replicas on the market, knowing that people will now catch on to the con. Then the people who bought the first ones at high price moan, because their valuable coin is now contraband junk. We use databases of known fake casts and die strikes, and then do overlay matching to compare them. Pull up the unknown specimen in GIMP or Photoshop, then pull up the known fake. Make the known fake to 50% opacity, and then slide it over the unknown. If they can from the same cast or die they will "click" together in a very noticeable way, indicating a fake. Forgers try to disguise the fake replica by using mottled color schemes and wear patterns, but the overlay technique ignores these tricks and shows the forgery. If you overlay the unknown "trilobite" above with the known fake from the paper, you might find they "click", and come from the same mold. Link to comment Share on other sites More sharing options...

In my Roman coin collection I have a couple of fake coins and they're pretty rough but they were forged by the ancient Britons at the time.
