Founded in 1930, Fisher Price has gone on to be one of the largest toy-makers in America. It has been part of Mattel since the early 1990s, and it brings in $1.7 billion in revenue each year. Fisher Price Coins date back to the 1975 toy cash register released by the company. The cash register was a huge toy hit.
At the register, Fisher Price made brightly colored fake coins to help children not only learn to count, but also recognize colors. These original 1970s Fisher Price coins are now worth hundreds of dollars, thanks to the nostalgia surrounding the retro cash register toy.
