Has this ever happened to you?
I saw a coin a few days ago on an internet dealer site. It was a beautiful coin for the grade. It was a grade I'd like to have. It was a series I am interested in collecting. It was a date and mintmark I need. The price was very fair. The dealer was known to be reputable. I want to buy the coin. So what's the problem?
I can't find it again. Worse yet, I can't recall which of the dealers I found it under. I have a group of dealers I'm willing to buy from bookmarked, but the coin has vanished. I don't think it was purchased by someone else because I can't find several other coins in the series that were on the same site I was looking at at the time.
It just vanished! Tragic.
