The unit of money in Lojbangug is the rupnu, which is divided into 100 fepni. The exchange rate is currently about 15 Lojbo rupnu to the American dollar. How come ? Who decided this ?

Lojbo have the odd habit of referring to everyone else's monetary units as rupnu too. To distinguish them, one can say merko rupnu or meryru'u for the American dollar, ponjo rupnu or ponru'u for the Japanese yen, etc. (ropno rupnu sounds especially fine!). To be absolutely clear, the Lojbanic rupnu can be known as a jboru'u or lojru'u.

The coins are:

fepni 1 fepni
mumfei / zinsi'i 5 fepni
dekfei / decru'u 10 fepni
niksi'i 20 fepni
xabru'u 50 fepni
rupnu 1 rupnu
cibru'u 3 rupnu
dekru'u 10 rupnu

(Boring. How about coins in powers of 2 fepni? Then you can always make change, never needing more than one coin of any denomination. 'What a great idea!' Or for real laughs, have the denominations in Fibonacci sequence, which would also require at most one per denomination for any number, just a lot harder to work out.) The sequence 1 2 3 5 10 20 30 50... also works this way, and would be much easier to work out.

(let me know if anyone misses the confused, pointless discussion that was here, most of which was my fault — rab.spir)

Incidentally, if the exchange rate really is 15 rupnu to 1 meryru'u, anything less than a rupnu would be an amount of money most people wouldn't even bother picking up off the street - less than a nickel. Not exactly worth making coins for it. Given that the phrasebook describes fepni coins, was it perhaps supposed to be the other way around?
