How much would a prehistoric stone sword cost?

I'll bet that it's not prehistoric, but I guess it may be very old.  You'd have to have it appraised by a weapons expert and/or an anthropologist/museum curator/private collector of some sort.  Without knowing its age or where it was crafted, nobody can tell you.

It's "worth" whatever a person is willing to pay for it.  It's estimated current value is about $40, but again it all depends on what collectors are willing to pay.

the Gurkha  knife correct name a KUKRI depending on the condition and age also whether it is genuine is worth  between £15 - £50

It's only worth as much as someone is willing to pay for it.  One sold in 2003 for $3,000,000.00 and supposedly there are only 5 known specimens.

More than likely 1 cent. Maybe more depending on condition, but still less than $1. Try looking it up online you should be able to find something.

Carbon Steel is probably your best bet, thats traditional.\n\nSome sword makers today use swedish powdered steel but I hear its really pricey but I like carbon steel better.\n\nI suggest you get some books on the forgeing of Katana, they are expensive books too.\n\nGood Luck, You'll probably need it, it takes alot of practice and experiance to make a good Katana!

Around $160-$180 for a carbine or rifle.

I just finished helping my son with the same project. We used cardboard, gold spray paint, glitter, a small wooden chest from walmart as the sarcophagus, aluminum foil wrapped in gauze for the mummy. He used orange and red tissue paper on toothpicks as torches, cut up straws as the jars in the treasury room, and cut outs of egyptian furniture pasted to the wall. We used playdoh to make the outside of the sarcophagus and an old pair of earrings as the flail and staff. And finally I used some type of cotton material to make spider webs with fake spiders. We used mostly what we had on hand. Total cost of putting it together was less than $10 and my son got an A!!!!

Not very much unless it is signed or has something else quite special about it.  These items were made in great quanities and there are many in good shape still around.  I would doubt you could get more than 25% - %50 of the origanal purchase price for it at this time.  The best place to check the going rate on such items is EBay.
