One of the most surprising valuables around your home may be cast-iron cookware. Worth from $15 to $1,500, this is stuff you rarely want to sell at a yard sale.
Fortunately, cookware is usually marked on the bottom with the name of the maker and the catalog or size number. Nearly anything made in the U.S. or Canada has some value, with old and unusual items by Griswold and Wagner bringing top dollar.

Oval skillets, waffle irons, Dutch ovens and roasting pans are worth from $40 to as much as $500 each. Holiday cake molds start at $70, but Santa brings $400. Griswold made more than 200 varieties of muffin and gem pans (a gem is a type of muffin). These can bring from $25 to $2,000 depending on which number it is marked with. A muffin pan called a Turk's Head will put $400 in your pocket.
Be careful, though, as there are two Griswold marks. The smaller of these, about the size of a half-dollar, is too new to have value. Look for the big four-inch emblem.
Ignore anything damaged, cracked, warped, or pitted on the bottom. If it isn't fit for cooking, it isn't fit for collecting.
