The final figure is set by US Customs and depends on where the piece was made and the kind of object it is. Many antiques over a century old carry no ordinary duty; most jewellery and leather goods add a single-digit rate.

A Showa-era Mighty Atom clockwork alarm clock in a green tin case, made under licence by Shin and Company, with Atom on the dial.
The Piece
The case is a flattened triangle in bright green tin, standing on three metal legs, with a chrome bezel and a small hanging loop at the top. Behind the glass, Atom flies across a desert under a pale moon, the hours marked in red. At the foot of the dial are the marks of NTV, Tezuka Production, and Shin and Company.
The movement is clockwork, with winding stems and a bell at the back. We have not timed the movement or the alarm. The back plate and fittings show dullness and some rust from long storage, consistent with a piece of this age; the face and the green case present more cleanly. It measures about 15 cm wide, 12 cm high and 8 cm deep (5.9 × 4.7 × 3.1 in). Allow a small margin on those figures.
Shin and Company produced a small line of licensed Mighty Atom goods in the Showa years. The green case is the less often seen finish. It is a clock for a desk or a shelf, and a piece of Tezuka design first.
