There were 1,710,946 1892 British Halfcrown coins minted.
There were many British coins minted with the inscription HONI SOIT QUI MAL Y PENSE. The expression is old French meaning "Evil to him who evil thinks". In 1892, there were only two British coins minted with this legend, the sterling silver Halfcrown and the sterling silver Shilling. Both coins have a similar design depicting a Crowned shield in a Garter. The Halfcrown is 32 mm in diameter. The Shilling is 23.5 mm in diameter.
There were no British Two Pound coins minted from 1888 to 1892 inclusive.
A British 1892 sterling silver Halfcrown (Victoria), uncirculated and in absolute mint condition could fetch up to £190 GBP. If it has been circulated but still in good condition, it might fetch anything from £10 to £85 GBP. The values quoted are the best possible for the best specimens in their grades, but may be significantly lower due to varying demand for the coin and the prevailing economic climate. A reputable coin dealer will be able to give a more accurate valuation based on inspection of the coin.
