The value will depend on many things. One method for determining: Get an estimate of fair market value by checking MORE THAN ONE online re-sale and consignment shop for the same item, and use an average of the prices found. Be sure to use SOLD prices, not asking prices. (some possible sources to check are: eBay, Etsy, Postmark, ThredUp, Union&Fifth, etc) Another: Take the item to a local consignment shop and ask them to value it and write a receipt for their estimate for you. Our local upscale consignment boutique will perform this service for free for up to ten items per year. Then, use the "Add it" option to include it in your donations, and note the valuation sources used as recommended by violini1. Be sure to keep copies of the comparisons you used for the valuation in case of audit.
