My father sent a few samples to the Archaeological Survey of India in Agra, as suggested by many, so thank you. Those of you who said they are Terracotta figures, you were correct. They are Portuguese Terracotta figures from the 3rd to 4th century. Though there haven’t been many accounts of such well-preserved Terracottas, they’re not uncommon for the area of Agra, as the Taj Mahal features many Terracotta designs and mouldings. I can’t believe I thought these figurines were nothing of value, and considered throwing them away. Thank you all again for urging me not to throw these away, notifying me about ASI, and warning me about scammers. For now, my family plans on keeping the figures in a safe place.
