This is a great looking coat size Civil War regimental uniform button. This is the button work by the 13th New York regiment of infantry. It has the number "13" in the center of the button face with the wreath around the numbers. The 13th regiment, also known as the "National Grays" was from Brooklyn and served three months in 1861 and then for three months in 1862 and then one month in 1863. The regiment later combined with the 40th New York infantry to form the 87th New York volunteer Infantry. The face has fine detail with an excellent amount of the original gold gilding remaining in the recesses. On the back of the button it has the original back and shank intact. It has the correct maker's mark of the Scovill Company of Waterbury, Connecticut. This is the style listed as NY49 in Albert's button book and as NY230a in Tice's button book. This is a great looking 13th New York coat button.
