A few quick tips to avoid becoming a victim to Bidding on a Fake Corkscrew:
-Don’t bother to bid on items "located in Argentina". NUMEROUS Fake corkscrews have been known to come from this region.
-Look closely at the pictures, heck ask for additional pictures, then compare them to pics in Corkscrew Books, or Corkscrew Collector websites. Surely you must have seen a picture of the piece you are about to bid on in some book or website!
-If you’re unsure, just ask a fellow collector to verify the listing. It never hurts to ask.
