Instructions
Do your homework before you start shopping. As with any collectible, the value is set by supply, demand and condition.
Visit estate sales and home auctions. You can find upcoming auctions listed in your local newspaper, and when they are selling the contents of a home, they often list them in the ad prior to the sale.
Shop antique malls and stores. You may pay top dollar in these venues, but you're more likely to find what you're looking for here. You can also get some history of where the tricycle came from.
Shop online auction sites. Internet shopping dramatically broadens your resources making it more likely you can find what you want. You will have to pay shipping charges, but that could be offset by the countless hours and gas money you'll spend shopping locally.
Talk to older friends, neighbors and relatives that may have a vintage tricycle stored in a shed or attic. Though their kids are grown and they no longer have a use for it, they also may have never thought about selling it. If it has sentimental value, they'll like the idea of selling it to someone they know.
Get your best deal at yard sales. This venue is the place you're most likely to find a seller who doesn't really know the value of their vintage items. You can not only score a tricycle but get it at a great price as well.
