I had looked for this fob on ebay and bonz several times before but it was always highly priced (IMO), and sometimes in poor condition, so I always passed.
Recently I came across one on ebay that was NWOT and offered at a reasonble price (again IMO.) I probably shouldn't have bought it, but I was drinking wine and just received notification that I had a small ebay bucks refund (a dangerous combination!)
I got her for $47 shipped and I think that is a good price, isn't she pretty?
Here is my Koi goldfish fob 6522 (from 2007?) I took pics both with and without flash because it is hard to photograph metallics accurately.
