Really depends on the date and condition. British half-crowns before 1947 are silver and worth substantially more than the ones dated 1947 and later. The ones before 1920 are sterling silver, worth more than the 50% silver ones of 1920-1946. But post a date if you want an accurate evaluation.

The Halfcrown coin was a part of the long redundant predecimal British currency system, and no longer has an exchange rate with other currencies. The coin represented Two Shillings and Sixpence (or half of a Crown, or 30 old Pence). At the time of Britains conversion to decimal currency in 1971, the Halfcrown converted to 12.5 New Pence. A Halfcrown GBP in 1970 had the purchasing power of about $2.04 USD today. NOTE - This historical conversion is the result of many calculations and considerations by a purpose designed program. The resulting answer should only be regarded as an approximation based on current exchange rates.
