    Coin weights are weights which were designed to weigh coins in order to assure their quality.

    The usage of coin weights, especially glass ones, goes back to Ptolemaic and Byzantine times.?Coin weights were also known in Ancient China.

    In Islamic civilization, where they are called Sanadjāt, coin weights are said to have been introduced by a Jew named Sumair in 694. Up to that point coins were only compared to coins of good quality. Islamic coin weights were made of bronze, iron, and later glass (considered to be unalterable). They bear inscriptions related to Islamic rulers and moneyers and are therefore valuable epigraphical objects.

    Coins weights were also known in the Carolingian Empire, where they were stamped with regular coin dyes to clarify their attribution. Islamic coin weights were introduced to Great Britain in the 9-10th century CE through the Vikings.

    My examples are considered to be early English Coin Weights. The first one is George III. It is 5 pennyweight, 8 grains. It is Counterstamped SK in tiny cartouche on both sides.

    This one is George IV, 1821 Royal Mint and it is also 5 pennyweight, 8 grains. It was used for gold guinea weight.

    This one is for the South Seas Co. it is a heavy weight for gold coins. It's very dark and there is a lot of light on it to get these photos.

    The top weight is on the left. The second weight is in the middle, and the heavy weight for gold coins in on the right. That silver thing on the far right is off my lawn mower. It needs to be replaced but it was enough to hold these weights on end to show them.

    That's neat. I always wondered how they managed to tell the quality of gold coins.

    Nice. I only have this one coin weight from Prussia. I know there are those that specialize in these but I'm not one of them.

    This is a Islamic glass weight. I did not think it could be a coin weight.
    It is very hard to photograph. It has a very slight green tint.

    Just a thought. Since it is glass, maybe a low backlight would enhance it in photographs.

    I did try that. It must be beyond my photo equipment and skill level.
    I mean it show the tint and impurities in the glass but no inscription.

    It is a glass weight and it looks Islamic. They did make them. I'm sure you read what was in my opening posts about Islamic weights.

    Nice article and what a wonderful collection of glass Coin Weights. I'm going to have to search to find a glass one at a reasonable price.

    Those glass ones are on the pricy side.

    I like your metal coin weight better than the glass ones.

    I can not believe the amount some of these bring. I'm also having a hard time with just how many types there are. It's strange that you just don't see or hear about them.

    I originally thought these two were Asian gaming tokens, but now I'm thinking they may be glass coin weights. What do you guys think? As for what they weigh, I have no idea, if i can find them in a reasonable amount of time I'll let you know.
