There's a line between uncommon and rare. Uncommon is a habit for me, rare I cannot afford.
Uncommon:
'85 Centurion Cinelli
'85 Trek 770
'81 Trek 957

The only thing even remotely rare that has passed through my hand bike wise would be the early "signature" Merckx I sold.
Even rarer would be a photo, which I can't seem to take well.
