Greek Coin With An Error?

He seems to be a very good dealer that has been selling many years, yet at the same time he had quite a lot of what I consider collectors sets and items. Like uncut rolls of dollar bills and mint sets, and only a few binders of actual unslabbed/uncased coins of more rare values. He had 1 binder that I would pick something out of every weekend that was usually 1800's US coins but even now I am surprised at how much he would undergrade some items (which of course I would buy) I have never made it to a different coins store/or flea market setting yet to really compare his set up to any other. Maybe I just got really lucky with him and should count my blessings.

He also did try most weekends to convince me that the error market was going nowhere and I should not waste my 2x2's on anything that seemed odd looking or was an obvious error.

He kind of told it to me this way: If I saw a television at the store and all the buttons were labeled wrong at the factory, would I buy it and hide it away because its an error? Kind of silly!
