United Kingdom · Due to the commonality of this design (introduced in 2008) and the lack of a visible date in the image, it is difficult to determine the exact year. It could be any year from 2008 onwards until newer designs are introduced or the coin is demonetized. The change in composition to steel plated with nickel occurred in 2011 for cost-saving measures, which can help narrow down the date if the coin's weight or magnetic properties are known.

Washington Quarter

United States of America · The exact year of issue is not visible in the provided image, as the date is on the obverse (front) side of the coin. Based on the composition (appearing to be clad) and common design, it is likely minted after 1964.
