I don't have my friends e-mail address, I will be in his area tomorrow, I'll stop by and talk to him. E-mailing it to him would be the easiest.
Just a note, don't try to clean the coin in any way. That will diminish the value. Also, there are a lot of so-called "coin experts" out there who use deceptive practices, they will offer "cash on the spot" to try to get you to sell them the coin if it really is rare and worth $$$, they pocket large sums of money this way, they take advantage of people's lack of knowledge. They are knowledgeable about their business, they know what they are buying. With the advent of the internet, it's easier to determine the value of objects like this, so do your due diligence and research!
