i need help picking an artifact for english class?

I have to pick an artifact and tell why it is important to me. for example, if it reminds me something, a special moment, a gift from some I love.
Please help me!
I only have an egg that my brother gave me when he came from my country, do you think that’s a good artifact. if I picked that what can I say about it. it’s like a egg with designs of El salvador. like indians, coffee. like the culture. I don’t want to be embarrased
