Collector plates used to be in high demand and a must-have in households, so they were highly valued. This was somewhere between the 1970s and the 1980s. Prior to that, it was a rapidly expanding market, but there was a downturn that altered the trajectory of collector plate value.
While many collectibles have skyrocketed in value and remain highly sought after even today, others are worth much less regardless of the artist or manufacturer. However, collectors’ plates will always be appealing to many.
