GSA silver dollar buyers

I was wondering how many of you coin collectors were lucky enough to buy 1 or more of these coins when the GSA had their sales.

I got one as part of the Mixed CC group, a very nice 1881 CC with a little bit of bag toning on the reverse. Not bad for $15.

My old man scored one back in the '70s. Didn't pay $15 though. If I remember correctly you had to send a bid into the US Mint for these coins and the minimum was $30.
