The best places to search for old items to resell for a profit include estate sales, garage sales and even the humble hard rubbish collection. Serious resellers also scour auction houses, where you can often find undervalued antiques and collectibles as well as online platforms like eBay, Facebook Marketplace, and niche sites like ThredUp for vintage clothing and accessories. Fetes, trash and treasure markets and car boot sales are also great. Of course, op shops always harbour unique items that often go unnoticed but can be lucrative if you have an eye for value.

Check out local auctions, both in-person and online, or explore storage unit auctions, where you might discover hidden gems among abandoned belongings. I often wonder how many times my extra special finds have been traded over the years, where they started life and how they travelled over time to end up in my hands. Being able to sell them to a serious collector is the best outcome for these incredible pieces.
