Sure looks like it to me in the feathers. it cant be a clash cause nothing on the reverse represents those marks and they are raised. also the wreath on the Reverse has some type of doubling whether it be MD or DD. I dont believe that there are no DD for 1888 cents maybe none have been discovered yet.
Tommy, Google Longacre Doubling. This should lead you in the right direction on this coin. Treashunt wrote a great article on it here. http://www.numissociety.com/content.php?135-Longacre-Doubling-A-discussion
Thanks for the link very informative, but I dont not have that type of doubling its not surrounding anything its only on one side also the doubled feather has a notch and look the N in CENT on the reverse.
