im trying to make something like this..

please dont get into technical terms because i really dont know much about metal and metal works.

id just like to know how to make a mold like that, and how much it would cost.

I’m not including the gold required for the button. Also, what should I use as flux when heating the gold in the crucible. Basically I have never casted with gold (or white gold as this case happens to be), only silver, and am wondering what I need to do.

My Dad worked for this company and he lost all info in a house fire. His retirement benefits is what we are trying to find. He worked there in 1960′s through 1970′s. The company has been removed and is now named something else.

It seems to be pig iron, about the size of a brick. It’s a third again as long as a normal brick. It has three square indentions in the top, about an inch deep each, and roughly 3″x3.5″ across. It has two bumpy areas at the ends, just an upraised spot. There are no markings, no grooves, and no way to pour anything in it from the sides, so I’m assuming this is supposed to be poured in from the top, like a very small, square ingot of some sort. It is bloody heavy, something like 30 lbs for this little thing. I haven’t been able to find anything like this anywhere, ‘net included. It belongs to my boss at work; he has two of them, the other with slightly deeper holes in it.

If anyone has ANY SERIOUS clue as to what it is, I will be your friend for life!
Actualy, it might be related to the railroad. The man my boss got it from got it from his father, who collected railroad stuff. Sorry, can’t post a pic, though. First, it’s not in my possession, and second, I don’t have a camera. I’ll try a drawing on the computer; maybe that’ll help.
Okay, how do you post a drawing/pic? I can’t figure this out! Can I post such?
