This circulated 1975 Roosevelt Dime minted in Philadelphia with a copper-nickel composition has multiple mint errors. 
 
These errors feature a broad strike that flattened all letters on the reverse side - except "RIBUSUN", also a missing clad layer on obverse side, and a doubled die obverse side with "LIBERTY" letters touching the rim. 
 
These imperfections all add up making it a valuable addition to any collection, especially for collectors interested in error coins and unique numismatic history pieces from the United States of America.
