Does size matter, my honest opinion!
Yes, size matters, we hear it everyday. But is large practical, that is the question!
Now it fits in your wallet.
We all know the money we have today, the money is made so it fits in your wallet. There are some differences in countries, where the American dollar all has the same size you can see the Euro that has a small size different.
Within my collection I can see that most countries adhere to this 'standard' size. We have to go way back to see that the size of banknotes is way different.
The smallest there is
Here's the Smallest Banknote of the World. The Guinness World Records book of 2008 listed Romania's 10-Bani banknote, printed in 1917, as the tiniest banknote ever printed. The dimensions of the 10-Bani note are 38mm in length and 27.5mm tall.
This one I do not have in my collection unfortunately.
The smallest in my collection:
The smallest banknote I have in my collection is the 1 VNA Lira Italian banknote.
The banknote is printed in 1944 and is 78 mm by 42 mm. Can you imagine having these in your wallet? You can loose them so easy!
The largest there is:
The largest legal banknote measures 814 cm² (126.17 in²), achieved by Bank Negara Malaysia (Malaysia) on 29 December 2017.
The 22 cm X 37 cm (8.6 in X 14.5 in) banknote were creating in conjunction with the 60th Anniversary of the signing of the Federation of Malaya Independence Agreement. The banknote is worth 600 Malaysian ringgit
The largest in my collection:
The largest note I have in my collection is the 100 Rubles from 1910 out of Russia. This note is 25.8 cm by 12.2 cm.
Design of the banknotes consist the various architectural elements of Art Moderne style. On the obverse is the text: «ГОСУДАРСТВЕННЫЙ КРЕДИТНЫЙ БИЛЕТЪ. СТО РУБЛЕЙ. (STATE CREDIT NOTE. ONE HUNDRED RUBLES) and the relief panel with text: «Государственный Банкъ размѣниваетъ кредитные билеты на золотую монету безъ ограниченія суммы (1 рубль = 1/15 имперіала, содержитъ 17,424 долей чистаго золота)». (The State Bank exchanges state credit notes for gold coin without restrictions as to the total value (1 rouble = 1/15 Imperial, equals 17,424 dols of pure gold). (dols; dolia = 44.435 mg)).
I am happy that they do not print these strange sizes anymore, you can see that the 100 Rubles note was folded several times, for the collection it is nice to have these strange sizes.
For this time we live in I am happy with the average size of 18.7 cm!
