Not easy to answer as antiques markets and dealers vary. Whenever I do rarely see Edo-period tongs for a candle holder, as I collect old lamps and lanterns and candle holders, I expect to pay JPY 2,000 to 3,000 for them. They may be more expensive in a shop in a city somewhere. Iron ones seem to be rarer than shinchu (brass). Open-air markets can produce bargains though.
So when I asked the dealer if he would sell the pair separately, he said 'No'. I didn't push my luck as I had never dealt with this guy before. But then he added that he wanted ¥3,000 for the whole box! Those little ribbed spatulas can easily be ¥1,000 each. Well, that was a no-brainer, so I snapped it up before anyone else could get any funny ideas! Didn't even haggle. To be fair, the tongs were in terrible condition, covered in black and red paint or lacquer or something so it took some time to chip that away and restore them.
