Portuguese coin - essentially UNC
Dutch coins 1973 x 4 between EF and AU, some light wear on Juliana's hair - the 1970 coin is borderline UNC. However these are modern and have little value beyond the silver content.
Loving Halfcrowns. British and Commonwealth coins 1750 - 1950 and anything Kiwi.
If it's round, shiny and silvery I will love it.
