Collector plates were a hot market several decades ago when many consumers purchased them as investments as well as decorative objects. However, instead of increasing in value, most plates turned out to be worth much less than their original price.
When the personalized plate program legislation was enacted in the late 1970s, other states charged a one-time fee of $100 or more for personalized plates. To make the plates available to more people, the state Legislature decided to spread that higher fee over the expected life of a plate, 7 to 10 years.
