It's a very nice period 18th century polychrome chest (3 or more colors) and obviously it's ALL about the paint when it comes to value. Naturally, original paint is more desirable and more valuable. It's usually easy to tell if a piece has been touched up or repainted because old chests should have dings, scratches, abrasions, etc where you see the wood underneath the paint, if any of those scratches or dings have paint in them.......
Another thing is, the lids usually suffered the most abuse as back in the day they were used for everything, from seats to butchering hogs so it's not surprising that many painted chests this old have little or none of their original decoration on the lid. The fact that this chest seems to have it's original lid, repainted or not, is a plus because many old chests have replaced lids.
