there are two references, "Lincoln in Numismatics by King and a newer one, "Lincoln's Metallic Imagery" by Paul Cunningham that would help. I had to join a local Library to get a copy of King several years ago from another Library 150 miles away. it isn't an easy reference to use, the Cunningham book can be found at Wizard but I haven't seen it yet.
here's some of the description from Amazon, but the book is 30 cheaper at Wizard, $70.
completely updated and expanded version of King's 'Lincoln in Numismatics'. Listing all known metallic exonumia bearing Abraham Lincoln's likeness, photos are featured with concise item descriptions, logically organized and easily referenced. This stunning hardbound book features 1600 new, full-color photos........................
by contrast, King was about 150 pages in a small format with no pictures.
As noted above”Lincoln’s Metallic Imagery” by Paul Cunningham is my-go to reference for Lincolnania. The Lincoln medal pictured is listed as Cunningham 09-380S, 31 mm, in silver. Also produced in several other metallic compositions. I’ll try to add a quick pic on the entry in the book.
