I looked at the reverse of the Sullivan coin and maybe there are similarities between it and the obverse of your coin. Interesting.
Fellers, I believe this is good. There are 3 types of thin planchet coins - rolled thin, split after strike and split before strike (there may be others, but these are the ones that come to mind). The OP's coin is of the last type. A split before strike has a smooth side (the original outside of the planchet) and a rough side where imperfections in the planchet caused the split. I can certainly be fooled and it's possible here, but I think we see so many coins here that have been beat to death by a pipe wrench that we are a little quick to declare everything as damage. Anyway, here's a "no doubter" for comparison.
I believe its something.....its hard to find similar pictures to compare it to... not always a bad thing.. aha.....http://www.ebay.com/itm/ND-D-Jeffer...519?pt=LH_DefaultDomain_0&hash=item2c97966b57
No, I really did not think you did. Just a little tounge in cheek humor because I really have no idea on this one.
I think it's the real deal also. The 2 rupee coin (on the link below, second coin from bottom) looks very similar. http://www.error-ref.com/split_plan_before/
And here's a split after strike . . . sorry I didn't get large images inserted . . . did a copy paste remotely from the website and linked from there. If I get back to the office with time remaining to edit, I'll link to large images.
