the 1993 and 1994 year lines with a round mint mark for Mumbai are wrong:

SCWC has it right:

They should be like this:

I don't have the 1994 variant in my collection, but I suppose my documentation also covers the 1994B coins? Thus we should open two lines for the Mumbai 1993 and 1994 coins
1 with the narrow diamond (wid, fine date)
1 with wide diamond (narrow, bold date)
Thanks
