Watch List notes:

USA Half Dollar 1866S No Motto Breen 4929, only Good but a key rarity in the series. The 1866S No Motto coin is extremely rare in all grades. The variety's very existence depends on a quirk of timing. The Act of March 3, 1866 stated that all silver and gold coins minted after Jan 1 1866 large enough to carry the motto 'IN GOD WE TRUST' had to carry it. The obverse dies reached San Francisco before the end of 1865, but the reverses did not follow until May 1866. In the meantime San Francisco authorities made 60,000 Half Dollars using left over reverses without the motto. Of these at most a few hundred survive in all grades, making this an extremely rare piece.

Estimate: 75-175 GBP
