Delhi Sultanate was posted as being a pert of India, which it was not at the time it existed. To say so would be to fall into the trap of Hindu jingoists. Most medievals and all ancients of which I am aware are already exempted from modern borders. I am not trying to mess up the games, but, in their own way, coins tend to be far more permanent than most national borders.
Well, of course john-charles. Generally, the way I've tended to play this here game, and the way I've seen most others do this amusing game, is play or allow a state no longer in existence to step in place of a polity as it exists today. For example, there is no longer a Margraviate of Brandenburg, or a Kingdom or Bavaria, or a sovereign, international entity called Hamburg - but we play and accept all of those as Germany. Nobody wants to fall into a Hindu jingoist's trap! I think everyone's intent here is to have fun, pass the time, see interesting coins, et cetera.
Construing Penang as Malaysia (no jingoism intended here), I shall move up to Brunei. A 2002 ten-sen.
