So I got this the a while ago and don't know what it all is

Your tintype was created from the original Goodwin & Co. glass plate negative which was recently auctioned by Saco River (attached below). The "Vermont Find" negatives also included a number of photos developed from these negatives, some tin types, others albumen. Some of the subjects such as Flynn and Doran have multiple surviving photos that appear to be early 20th century creations from these negatives. Others contend that some of these surviving photos could be 19th century. While the original negatives are historically significant and directly tied to the cards produced and distributed by Goodwin & Co., the photos are generally accepted as later creations and not valued as much.
