Shah Jahan Mughal Multan Silver Rupee Coin Rare XF

Your avatar is one of my coins. I paid AU$15 for it from a dealer at a coin show back in 2001.

Shah Jahan ruled from 1628 to 1658 AD. He was the guy that built the Taj Mahal.

The Mughal rupee is silver; the standard fineness is .916 fine, though the actual fineness may vary slightly, depending on the mint. Standard weight is 11.44 grams.

In almost all cases, the actual date appearing on the coin doesn't affect the catalogue value, because virtually nobody is trying to collect these coins by date - the mint is far more important in determining value. This particular type of coin (KM# 235) was struck at over two dozen mints. Mine was struck in Lahore (now in Pakistan), one of the most common mints. Scarcer mints like Kabul (now in Afghanistan) are worth more than triple what I paid. The mint you mention, Multan (now in Pakistan), is only slightly less common than Lahore; my 2003 edition of the 1600's Krause catalogue lists Lahore mint coins at $18 in EF, with Multan at $24 and Kabul at $65.

A Multan mint coin is not "RARE" by any reasonable definition. I'd think $30 to $40 would be a reasonable current book value.
