According to coppercoins.com, there is one DDO and one DDR, very minor and hard to spot, don't forget those. Also, that is a unique RPM, a D over horizontal D, that doesn't happen very often, usually just a slight rotation or slight shift. Great that you have more, offer for sale on eBay(like I described, should interest some!) 
Then like me, have to decide what to do with all the others...need any 1963P's?
