Specimen. (1) A sample piece; when the word is stamped into a numismatic or medallic item it means it was not issued but used in some other way (as a manufacturer's sample, say, to show prospective clients). Decorations supplied for, say, an exhibit are so marked to indicate the item was unissued, not issued to a recipient.
