Well, you have just proven a point to and for everybody benefit. That is, whatever dice you have, expensive or not, you'll get the same kind of roll.
I want also tell something different about dice that is actually true and verified, scientifically, though I don't remember exactly ... well you'll see.
If you take two six sided dice and you roll them together and you put the result on a chart, you'll get, if I am not mistaken (this is where the "I don't remember which is which" comes in), You'll get a curve line, meaning, the probability you get a 7, a 8 or a 9 is higher than the probability you get a 2 or a 12.
If you roll them separately, if I am not mistaken, you'll get a straight line; meaning, you'll get an equal chance to get a 2, a 8 or a 12.
Check it. You'll see.
