He requests you e-mail him for an exact price list but has the following to say about what he is willing to pay for non-silver Franklin Mint plates "Generally $2 each and up with box / documents; $1 without box". He has this to say about collectible plates in general: "The market for modern ceramic plates is VERY limited. Despite the so-called limited edition status of these plates, there basically are too many plates for too few collectors, resulting in a low price for most plates. I have SOLD large lots of mint-condition, in-the-box limited-edition ceramic plates in the $4 each range."
