These dual-purpose candle holders could be used on the table or hung on walls as sconces. These surface a bit more often now than they used to, but I've never seen versions where the crescent moon is only an outline. All others I have seen have silver moons. Does this make a material difference relative to value? In my opinion, no. Sustainable guide value is $175 each.
10/29 Update: The pair sold for $405, somewhat above sustainable guide value.
