Why were these two very different coin types issued in the same year?

They are of the same size and metal. Only their weight differs by roughly half a gram.

Who knows the reason for this?

According to this page...

http://www.chiefacoins.com/Database/Countries/Lebanon.htm

These are..
KM#22 10 piastres. Year: 1955. Weight: 3.57g [3.60g]. Metal: Aluminum-Bronze. Diameter: 21.50 mm.
and
KM#23 10 piastres. Year: 1955. Weight: 3.42g [3.45g]. Metal: Aluminum-Bronze. Diameter: 21.50 mm.

(NOTE: Other details are given.)

The "x.xxg [x.xxg]" I understand to be..

observed mass in grams [legislated/intended mass in grams]

..so still a difference in masses even if small. Odd for there to be such a difference.

Also, of course, different minters.

But the question is - WHY? Could the two different mints be a clue?

Both were minted in Paris. Several coins of modern Lebanon have frozen dates and these two seem likely to have frozen dates also. My guess is that N 10514 was issued first, because it carries the marks of the Paris mint and its director.

During the second world war, France lost political face by surrendering to the nazis. It withdrew from Lebanon in 1949. The marks may have been found too reminiscent of colonial times.

So we must look further for a reason.

But perhaps we will never find it.

Unless somebody knows any Lebanese numismatists?

Schön gives the same weight and diameter for both coins: 3.5 g/ 22 mm but slightly different composition (Al9-Bro for the Paris coin, Al8-Bro for the Beirut coin). US mint report says that the Beirut coin is minted in 1955 and the Paris one in 1955 and 1956). It gives 1.5 g for the Beirut coin (probably incorrect?) and same composition - Al9-Bro.

The Beirut coin is minted in SOMP - Société Orientale des Métaux Précieux S.A.L. It still exists. From its site: In 1955, SOMP minted for the Lebanese Finance Ministry 5 piastres out of a magnesium / aluminum alloy and 10 piastres out of a 92/8 copper aluminum (Aluminum bronze) alloy.

Very good. But the question remains: why TWO different designs and types in one year?

See reply #5. One was a colonial issue, the other a post colonial issue. Dates are frozen so they are not significant.

Not that I know the answer ;) but I found it interesting that, according to Allnumis, the first one (ship at the top) was minted in Ibagué ... by the Casa de moneda de Colombia.
