BRUNEI: Anonymous, 18th-19th century, tin pitis (3.16g), SS-15Dvar, camel facing left (not right), floral scrolls above and below // Arabic honorific title al-sultan al-'adil malik al-zahir within 4 interlocked clouds, blundered symbol in the center; weakly cast, EF, RR. The proper weight of this type seems to be in the range of 9g to 12g with an average of about 10.5g. These light pieces are probably local issues, produced with or without official authorization. They seem to be considerably rarer than the full-weight examples.
