Here is a CD 136 EIN [010] (F-Crown) B & O. (R-Crown) PAT. JAN 25TH 1870 SB in unlisted Blue Aqua. Condition is excellent with only an open base bubble, a small ding/flake on the rear upper wire ridge and three or four pinpoint tics in front. I say front and rear, but the crown embossing, which is very faint, is rotated to the point that the 1870 of the rear embossing in actually to the front side of the left mold line putting it on the "front" portion of the crown. The B & O. of the front embossing ends almost directly above the right mold line, so while it is still on the "front" portion of the crown, it is as far to the right of the front crown as it can be. I don't know whether this a common phenomenon or not with these old soldiers, but it looks pretty cool to me. Asking $15 plus postage.
