Gold and silver coins have been worth cash based on the metal value, but recent increases in the price of gold and silver make vintage coins worth more. Overstrikes and production errors also can bring extra cash for coins without significant age.
Don't assume that you didn't pay much for an original work of art, that it's not a valuable financial asset. Andy Warhol prints sold for a minor outlay during his lifetime, but works done by Warhol now bring millions. Investigate your art before giving it away or donating it to charities.
While most vintage pocket watches bring between $20-100, some rare models or handmade models have value in the thousands. Condition is everything, but don't assume that a watch that won't wind is broken. Watch works need lubrication, and it's best to avoid winding until you have the watch cleaned by a professional.
Most best sellers have little value due to the number of copies produced, but some have value. Look for good condition, first editions and a dust cover. Add a signature by the author and you may have a modern treasure. Look carefully at books inherited from relatives, even works done in the 1960s and 70s.
Vintage kids toys and games have value, but modern toys can grab high auction prices. The highest prices go to working toys in good condition and items with the original boxes and packaging.
