Tips For Making The Most Money Off CollectiblesStick with the real thing
Replicas will never be as valuable as authentic merchandise. Collectors want the real thing, not a copy. Also, stick to tried and true classics that have a built-in demand. Avoid the "sleeper" collectible that you think will fetch a fortune. Chances are you would lose more money chasing after the sleeper than with investing in memorabilia with a proven track record of returns.
Display collectibles properly
Just like curb appeal helps in selling a house, properly displayed memorabilia will be more attractive to a potential buyer. You can find display cases for any type of sports collectible: jerseys, baseballs, footballs, diecast cars, and more. Display cases also act as protection from wear from handling as well as protecting any autographs.
Do your homework on the proper value of your collectible
Look online or check out auctions for comparable items. Know what to look for to determine the signs of a valuable collectible (brands, markings, signatures, rarity of the item, date produced, etc). If you have a special item or are still not sure, enlist a professional to help appraise and authenticate your collectible. Often, they will be willing to help you sell it for a fee or share of the sale.
Pick the right marketplace for you
Chances are you won't get top dollar for your rare memorabilia if you decide to put on a yard sale. Because of this, look for mediums that cater to serious collectors with money to spend. Try listing on eBay or even cosign to an auction house if you'd rather get rid of everything at once. Reach out to collector clubs in social media and post on their forums about what you have to offer.
