If you are going to list online then thats where you need to check prices !! Check ebay for sold items and the other sites such as Ruby Lane and Etsy !! Just keep your prices in about the same area !! When selling items that are nice but not unique,,it is just a matter of presenting them well with a good description noting any flaws !! People will buy or not as their taste dictates !! Some will like them others may not !! Its a matter of personal taste !! Wouldn`t hurt to throw in a few ideas of how they could be used !! Like ( Beautiful matched set of Satsuma jars circa late 1800`s or early 1900`s !! Would look lovely sitting on a fireplace mantle or hearth !!) Don`t forget to add the size of the jars !! I am guessing they are about 10 inches tall ?? If not then decide where you think they might be used !! It helps to give people ideas about what you are selling !!
