Queen Anne half-crowns dated 1707 and 1708 belong to the post-Union coinage period. The exact variety and mint can affect identification and value.
What to check
Look at the date, portrait, edge and mintmark. The letter E can indicate the Edinburgh Mint on relevant post-Union examples. Use a specialist reference to separate varieties before comparing prices.
Value guide
Condition, variety, authenticity and demand determine the price. Compare recent completed sales of the same date, mint and grade. A description such as “rare treasure” is not evidence on its own.
