TIF and Doug are playing devil's advocates a little too well. Especially for some of us balancing rather precariously on our pedestals.
How we price our goods and services is an interesting subject. Artists that strike me as having no particular merit offer their creations at prices higher than others I find gifted. That does not mean they are crooks but it does not mean I will be buying them either. In this case, I have never seen a coin listed that I thought was a fake judging only from the photos. He regularly ID's items correctly. He ships promptly. The complaint we just can't get over is the 80-90% discount required to make a coin possibly of interest. Last night I invested several hours looking at his listings and found nothing I needed. I did not see anything that I found wrong beyond the prices. Now I think about the paychecks and retirement checks I have received for what I did for my employers and have come to the conclusion that I should not throw stones about seeking to be overpaid. I give a lot of free advice here. I suggest you take care not to overpay for it.
That you're so free with your knowledge and advice is why you are one of this hobby's more excellent finds... kind of like some of the coins themselves. This fellow on the other hand, on my own personal grading scale, I rate as one of the culls.
