I'm looking at a gold Dinar to purchase. Seller indicates its weight is over 4 grams. Most I have seen on the internet weigh closer to 3 grams. Is there a typical weight for these coins? Anyone know the typical fineness of these coins? It is supposedly from the Seljuq Empire, about 1072 AD. The offer price is really close to melt value if it is anywhere near pure gold (gold at about $41 per gram). Sorry for lack of details, but I've been burned before asking questions before buying and losing the item. Rob
