Australian Half-pennies -
All coins were found while cleaning my stepmothers home as a part of my inheritance ... I have no idea what they are worth but would be enormously grateful if I could gain some idea if someone can help. They have not been cleaned but do carry the test of time with alot of green coating and I am hesitant to attempt to clean them in case this devalues them. Can anyone help?
