Williamsburg salt glazed pottery

I'm selling a set of colonial Williamsburg salt glazed pottery, a 7 1/2 inch tall vase, a mug, & a candle holder. All 3 are gray and hand-painted in cobalt blue. These pieces are priced between $6 and $30 each on eBay, depending on their age & the design. I have had them for at least 30 years & they weren't new when my mom gave them to me but I'm not sure exactly how old they are. They are in perfect condition with no chips or cracks. I will take any offer over $15 for all three. Thanks!
