I've pulled quite a few nice lil' 80's MS cents from boxes in my time searching too... It's not a bad hobby (searching boxes). You generally get 20% copper to throw back, and some really neat easy to find varieties (wams, dd's, etc...), and then these to boot ! NICE finds btw,,, and only $.01 per coin !!
I save AU coins to re-search for something new in varieties or to give to a new collector starting out.
Nah, just some typical split plating. You'll have to come back to the house sometime and I'll show you my Memorial binder Ken.
