looks like MD, i've found a number of similar cents roll searching were the entire reverse including building showed MD...
Believe it or not, there are a few people that collect extreme MD. You might want to hold on to it. If nothing else, a nice example of MD. However, if you describe it correctly, you might get $1 or $2 on eBay. If you don't believe it, and I understand why, do a search of sold listings with MD. It amazes me everytime I do it.
I have a couple of 1980's with extreme doubling on the date and I had a '69. I think I lost the 69 though.
I also, have had no trouble selling lots of 20 machine doubling coins on ebay. It does not always have to have a lot of value, some people are just interested in these types of coins.
I had a very extreme although beat up 1969. I always thought someone might want to dupe someone with it. I put it back in the Coinstar
