I don't think so, but I guess that's just how it is. A while ago I made enquiries about viewing Australia's national coin collection, held by the Royal Australian Mint. The public aren't allowed to view it, though apparently dribs and drabs of the interesting stuff are displayed from time to time. Strangely though, Museum Victoria seems to have publicly available photos of its entire coin collection - a fairly comprehensive collection of British Empire coins (including the Sydney Mint and Melbourne Mint collections).
