For those of you who have dollars or Euros to exchange into Libyan Dinars, the best place to exchange is in the local gold markets. Although you can do it in the banks, you can normally get a slightly higher rate in the gold market.
Is there a fixed rate?
Make sure that you ask around to a few different sellers before you exchange your money. I have found that the rate varies depending on who I asked. Also, you might be able negotiate a little better rater if you have more money to exchange.
One thing we ran into when we first started changing money was that the sellers wanted new bills. When I presented them some “older” $100 bills, they reduced the rate on me. If you have crisp new bills, you can get the best exchange rate possible.
