I don't think it is coin marks, say, from being at the bottom of the bin, usually on those, there are larger reeding hits, which are easy to spot. Whatever contacted it reverse, you can see miniature scrape lines off many of the circular areas. The letters, reverse, and bridge, strangely, are blemish free, while the sails do have a handful of blemishes. On Obverse, everything looks like 150 grit sandpaper, letters, date, fields, and Washington, but, again, are RAISED..not a single incuse blemish Obverse...very weird! The coins I've seen with multiple contact marks usually look pretty much the same on both sides..not this one.
