Supporters can bid for the shirts, which are signed, feature embroidery and Carabao Cup sleeve patches and come with a certificate of authenticity, to raise money for the appeal, which was chosen in memory of former player Christian Atsu, who tragically lost his life in Turkey's devastating earthquakes last month.
The Red Cross Earthquake Appeal helps the Turkish Red Crescent (Kizilay) and Syrian Arab Red Crescent emergency responders who have been working tirelessly to help people affected by the earthquakes, providing first aid and essentials like food, water, blankets and shelter.
Although the shirts were prepared for the match - Newcastle's first major final in 24 years - they were not used as the Magpies were beaten 2-0 by the Red Devils at the national stadium. The auction is here.
Worldwide shipping costs are added at the checkout for each product won. The auction closes at 2pm (BST) on Saturday, 1st April.
