- an inexpensive sacraficial anode is the old 1-cent penny. the exterior
- of pennies since circa early 80s (don't recall the exact date... you'll have
- to ask a coin collector) is copper plate, but the rest is zinc. i think zinc
- is also used in cathode-anode passive electrical rust protection. sanding
- off the copper will reveal the zinc interior.
- i have used non-U.S. pennies for such purpose in ocean eng. buoys.....defacing
- US coinage is a violation of federal laws..... so use foreign coins (unless
- you can get some zinc elsewhere. my 2 cents worth... :-)
