I had one. I found it in circulation in the fifties. Not in real good condition, but it was something I kept for many years.
Okay, here's my biggie. 1856 PCGS MS-62 S-3 Note that it's an MS rather than a PF. The S-3 variety is considered a business strike.
For those that might be interested, The FLY-N CLUB will be having a meeting at the FUN show in January. Everyone is welcome. Rick Snow and Charmy always have fun information to share.
Almost any Flyer is going to be an anti-climax after that one. Here's mine, which lives in a PCGS MS-63 holder. I'll probably have it reslabbed, since I can't seem to remove the smudge on the reverse plastic, and I may see if I can have the verdigris stabilized at the same time:
I only own one, for my typeset. Graded NGC MS-64 PL. Prooflike Flyers are super rare, but this one has very attractive reflective surfaces.
