I bought 3 of these for 50€, roughly 75USD. That makes them worth about 25$ a piece.
The A560 is slightly higher in value, be it because they are a little more rare then the A2060.
Forget about any "industrial" applications for these cards, hardly any industry still uses ARCnet, let alone Amiga's in them.
You might have a chance selling them cheaply to amiga fanatics (like me) who want to hook up a bunch of Amiga's together without having to spend big bucks on Ethernet.
