OP's question reminds me of an inspirational poster I saw in high school.
It said, "A ship in a harbor is safe... but that is not what ships were built for."
Ya gotta take risks if you hope to get lucky, friend. I think I would buy it.
I bought $1000 of dimes from a coinsorter (as my first foray into dimes) and came up with 7 silvers. As I rolled the dimes, I found they were about $15 short somehow. I was upset at the time, but with the price of silver now, I came out ahead anyways.
