These are the decagonal (10 sided) safety style wheel nuts for the wire wheels on the classic Aston Martin DBS6 and Vantage cars with wire wheels. According to the parts book these were used instead of the typical winged or eared style on cars destined for USA, Denmark, Germany, Switzerland, and Australia. These are the larger 52 size hub so would fit DB6 Mark II also. 2 left and 2 right. Decent condition, a bit scuffed and dinged as shown.
