I've got 30 large electrolytic capacitors (like soup cans)
to sell (12,000 and 8,300 µfd, working voltage 100dc,
purchased as new surplus), and they've been sitting is a
cabinet for 20 years. Is there a simple way to test them
to see if they're still good?

Yes. But possibly pointless. See below.


Any suggestions on where a
guy could sell a third of a farad of electrolytic capacitance?

Cap sizes have shrunk so much, you'll only sell these on ebay as NOS for
repairs.
