I'm having trouble separating the two questions here: do you want to get away from the dollar, or do you want ready cash?

If it's the first, why can't you just buy into non-dollar-denominated funds with your IRA?

If it's the second, and if you're able to roll your IRA into a 401(k), then depending on the trustee you could loan yourself half of it in cash.

Alternatively you could probably create an ESOP for your company and (again, trustee permitting) invest your IRA or 401(k) into that.
