Hello,Welcome to our site and thanks for your question. My name is XXXXX XXXXX I will do whatever I can to help you.
You would need to consult an Egyptian attorney about this. By law, all antiquities in Egypt are the property of the state. A local attorney would be able to tell you if you could sell the items on the property at all.
It would not help to have pictures. I would suggest you employ an attorney in Egypt to prevent dealing with unscrupulous explorers. You could also contact an Egyptian museum for their guidance http://www.touregypt.net/egyptmuseum/egyptian_museumx.htm
No one at Just Answer can provide legal advice or put you in touch with someone who can explore in Egypt. For your own safety, you should contact an attorney.
