A Serbian man is just one short of collecting every currency in the world.
Zoran Milosevic has spent 36 years working on his quest of showing ''how small the world is because you can lock it [all the currencies] in a box of 1.5 m2 [11 square feet]''.
The man - who has relied on the generosity of holidaying family and friends, and occasionally ordering online - has collected the currencies of 194 countries so far, including some no longer in use. Now, he is just missing the Solomon Islands dollar to complete his collection.
Tracking it down would ''prove what can be done by human perseverance'', he said.
