Group of 3 Prehistoric Discoidal Stone Tools (Hammerstones / Percutors) Culture Prehistoric Dating Neolithic – Chalcolithic period (circa 6th–3rd millennium BC) Description Group of three discoidal to ovoid stone tools, carefully selected for their mass and resistance, typical of prehistoric functional implements.

The surfaces show clear ancient wear, with rounded impact zones and natural patination developed over long-term use. No modern shaping, restoration or recent alteration is visible. These types of tools are characteristic of prehistoric domestic and workshop contexts, particularly from the Neolithic to Chalcolithic periods. Dimensions Largest piece: approx. 13 cm Smallest piece: approx. 10 cm Condition Good overall condition. Structurally intact, with ancient use-wear and no modern damage or repairs.
