Egyptian coffin fragment

[lasse b]

Hi.
my first post on the site, been looking up coins here for a while, and saw one day
that there were some egyptian antiques.
I have in my possession a rather large piece of an old coffin fragment, which i was told was from the ptolomeic period.
can anybody here please help me identify and maybe put a price on my piece

thx alot ahead :-)
