Many, many thanks for this Pete, you went above and beyond what I asked, lots of great info that I wasn't aware of before. I'll be reading this over this several times to help me determine how to proceed forward.
For this purpose I was wondering if you could clarify two points in your post, if you have the time.
You wrote: "Forget what prices dealers sell for as a private seller is not always likely to get the same."
Do you mean that I will typically get less when selling a coin than a dealer would get for the same coin?
You also wrote: "You should however always show clear photographs or if selling a bulk lot perhaps avoid stating condition other than regular bullion meaning subject to small imperfections, spots etc."
So if I understand this correctly, if I sell a bulk order I should state the condition as being "regular bullion"? But I don't need to state the condition when selling individual coins, because there will be a clear photo of that specific coin? In that case, what if I make an ad for selling a coin, but mention that I have 20 or so of that coin available - do I need to show pictures of all 20 coins, since it's not really a bulk lot because I'm selling the coins separately?
I hope I was able to communicate clearly what I meant. Thanks for bearing with me, thanks again for your terrific reply, and thanks for welcoming me to the club!
