As mentioned all companies run under different company rules. For example, some will not sell pornography, alcohol, and ammunition, broken, chipped or greasy items. Some will not sell some types of clothing as well, like used under garments, socks etc… Many vintage clothing items do have value so donating them could cost the client additional funds. So generally speaking all things that are in good working order, clean, vintage, and unusual or antiques have value. Some have more value and others less. But it will also depend on the market and location of the sale.
