There are two light blue coasters & two darker blue coasters. The blues blend but do not match. In the picture of all 4, the two on the bottom are the dark ones & are the older ones. The blues can appear grayish in low light. Excellent vintage condition. No chips, cracks, damage or repair of any kind. Please look at my other listings of high quality Pigeon Forge Pottery pieces. Consider bundling. I am liquidating my collection. A short history: This much-loved pottery flourished in the Great Smokey’s tourist spot, Pigeon Forge, Tennessee - just a few miles from Gatlinburg - from 1946 - 2000. During the last half of the 20th century, the Pigeon Forge Pottery made its mark on the culture of the Great Smokey Mountains by working with materials from the region, by hiring local artists, and by creating designs inspired from the flora and fauna of the surrounding mountains.
