I can answer one of your questions. You shouldn't send the coin in to be graded/slabbed. Its probably only worth in the $10 range. I probably wouldn't worry about grading a coin unless its worth $150 or more or if you think the coin has a possibility of going MS67+. That's just my opinion.
I can not tell from the pictures provided whether or not it is DDO-1 or not. The pictures look over processed. Not sure if you are editing them but you shouldn't. Try to show us what you are seeing that makes you believe it is DDO-1. Also there is a die chip on the reverse of that DDO. If it is not there that doesn't' necessarily mean its no the DDO but that could verify that it in fact the DD0-1
