First, cover a coin in plastic .
Then, pour cement over top of the coin.
When the cement is dry, take out the coin.
You now have a mold.
Heat up some metal at a very high temperature.
Pour it in the mold .
You can make engravings with a sodder  iron.

Do not cast into concrete, the concrete and the molten metal could explode due to the retained moisture within the concrete turning into steam, creating expanding air pockets. The concrete will become shrapnel, the molten metal will fly out and melt through flesh.
1) How do you build a dye (not die) or mold? 
If you want you can use clay as the material then fire it up. Anyway, on your preferred material, engrave your design on it (which will take a while) and let the material harden (if it was a piece of solid metal, then don't bother letting it harden (makes no sense anyway)).
2) Which is best, the Roland RX-50 or MDX-15? 
The RX-50 is $5000 dollars. You can make 10 liquid nitrogen generators with that much money. It could make 3D things out of anything. MDX-15 is cheap, but it won't use metals (as far as I know), and it takes 3D scans from popular 3D software (I think). The RX-50 has a built in scanner, but you still need separate software to use it. 
3) What is a collar dye and how does it work?
I have no idea... 
4) When I mint, do I use oil? 
You don't have to.
5) I know I'll need a press, how do I build one?
You don't need fancy hydraulic equipment. (see image 1) Just use a simple force multiplier. 

What I don't get is "the engraver must be a desktop". What does that mean?

you can engrave a steel plate with the design of your choice with a rotary tool.  You have your plates, now pick up the 12 ton press at harbor freight and tools for $70.

"i need help i want to mint a coin,how do i build a die or mold? what do i need, how do i do it ?"
-What is your skill level and how many tools do you have?  A simple hammered die doesn't take much, trying for a modern coin is more exacting.
"which is best the Roland RX-50 or MDX-15 ? i want to scan it and engrave it."
-Sorry, I'm a hand-tool guy : )
"what is a collar die how does it work, do i need it ?"
-A collar is used to keep the edge of the coin flat or give it the reeded/groved edge.
"when i mint do i use oil?"
-No, but you might or might not when engraving the die.
"i know i'll need a press how do i build one?"
-Look up '20-ton hydrolic press' (sorry about the mis-spelling).  If you are going for the 'primitive' hammered coins, you don't need one.
"i want to do all this at home, i'm looking for small things..the engraver must b a desktop.."
-Depending on the detail, you can punch and/or grind the die into the head of a bolt.  The term is 'hobbing' and is still used in mints after the master die is created.

Here is how to make a two part mold.
