1/4 Dinar

Libya's quarter-dinar denomination has always occupied an awkward place in the series — too small to carry much transaction weight in a petrodollar economy, yet retained through successive issues for pricing legacy goods and state-subsidized commodities. The 1990 issue appeared at a point when Libya remained under significant international financial pressure following the 1988 Lockerbie bombing, though day-to-day printing and supply arrangements with De La Rue continued uninterrupted.

The watermark is the sole security feature — no security thread, no fluorescent printing. Modest specification for a De La Rue contract by the standards of the period.
