If you are traveling post rv,, then your total 'worth' of dinar has drastically changed and you are required by law to report it. Whether you do or not would be up to you. You could try to just play dumb and not say anything 'thinking' that the value was still <$1500 and hope you dont get checked. But if everyone and their brother is making a B line for the US, and an rv HAS happened, you can bet your ass that customs will be scrutinizing each and every passenger coming from that AO looking for just that. I've personally seen what the dinar looks like when it goes through the xray machine, and even though it only "looks" like a small book or bundle of papers (no other identifying features show up on the xray, ie metal strips), if an rv has happened and the customs agents have been made aware of it and told what to look for, it may not be as easy to get away with. You may be better off doing what p71rock suggested and use a courior, you just have to weigh the risks of all options.
