And that tends to overhype something and make people who really don't know the difference spend hard earned money on something that's not really deserving of a 'story' to sell it. Sell something based on its difficulty to locate, not on trying to make it something it is not.
The REAL story here is that in every bag of 5,000 wheats I go through I run into at least a hundred of these that are visible to some degree or another and recognize they are very common. I would consider it less than honest to try selling them at a premium just because I could. It's just wrong.
Just because you can 'make' a market for something doesn't mean the whole truth is disclosed. It also doesn't mean the purchaser has the experience to know whether the story is the whole truth. Get two people who don't really know the facts in a bidding war and a
Three Cent coin can sell for a lot of dollars. Doesn't make it worth that, and doesn't make it ethical on the part of the seller.
