Buying from a reputable dealer beats sending stuff for authentication. When I purchase a coin from
Forvm, for example, I will print out the web receipt, and overprint the image file of the coin and that serves as my archival reference.
Same with other reputable sellers.
I discourage venturing into the
eBay unknown Joe, no matter how much
quality rating they have. Some reputable sellers do also offer merchandise on
eBay, and that would be
fine too.
I purchased from random eBayers in early collecting period and ended up with
fakes or altered coins. I don't look forward to the anxiety of this. Fortunately, on the one
fake I purchased, and another I recall
had some sort of
nickel plating, both I got refunds.
One one of my early purchases on
eBay, I
had significant amount at stake and found out when I received the coin the vendor was international....
I sent it to David
Sear and was successfully authenticated, but the process was painful.
Good luck!
