not sure what someone means when they says worth 10 to 25 cents each. Maybe that is a dealer's price for purchasing a big lot. But I just looked on eBay
for the Lake Placid covers ... all priced from $3 to $40, several addressed, and many in double digits.
It's important to look at the SOLD listings not the active listings and see what people are actually paying. Anyone can list anything at any price... doesn't mean it will sell.
