Vintage toy guides might estimate that a Fisher Price 996 Airport is worth $75, or the 915 Farm is worth $25. These are typically starting points, but many factors impact actual value, such as the venue of the sale, the condition of the toy and the condition of the packaging.
Price guides do not guarantee values, but they can set some expectations. The airport may not bring $75, but the collector may expect that, in a similar venue, the airport is worth approximately three times the value of the farm. The actual worth of any vintage Fisher Price toy is determined by the price the buyer and the seller agree is acceptable.
Some collecting websites refer to online auctions, and collectors may get some ideas of value of specific Fisher Price toys at a particular point in time.
