This is a CD 135 Chicago with EIN [020]. Embossed up on the shoulder: CHI. INS. CO. / PAT.OCT. 16. 1883. PG shows no period after 1883, this one has the period. This is in the normal color range for these: blue -aqua. The best condition one I've owned. One of those 'Must Have' CDs! Not too expensive for newer collectors either.
