The last type of pewter marks is represented by the merchant’s marks. It seems that the medieval pewter alloy reveals scratched symbols which are considered as being the merchant’s marks. Unfortunately, the medieval pewter is very rare.
During the 18th and 19th centuries and once with the success of mass manufacture of household pewter, the makers around England sold large amount of marked or un-marked hollowware and flatware to retailers and wholesalers located in the major cities. However, in the case of un-marked pewter the retailers and wholesalers stamped their own marks and creating confusion among pewter collectors.
In addition, some of the merchants have developed their marks as good as their touch marks. In most cases there is reliable evidence that these pewter marks have been applied the pewterer itself when the piece was created.
