    Rust deposits

    Hi again, I was gifted another mixed bag of predecimals this month. Got all excited. First item out of the bag was ... a rusted dog tag. Heart sank. I now have a bunch of coins with rust deposits partially obscuring everything. I attacked a few with acetone, a cotton wool bud and a cocktail stick to see what would happen. After three hours work I was able to rescue most of a german 5 pfennig but got quite high during the process so I'd rather not repeat it. (I'm kidding, the room was ventilated - I just got really bored). Next step, olive oil bath. Or will that most likely be a waste of time too? All tips gratefully welcomed.
