Looking for the lowest monetary value in your collection

Country: São Tomé and Príncipe
Year: 1977
Value: 50 Cêntimos
0.50 STD = 0.000020 EUR = 1/50,000 €

Is this coin still in circulation? can you buy something with few of them?

I know venezuela has this https://en.numista.com/catalogue/pieces4534.html, but you can buy anything... and actually not in use

Mine would be this one, which equals to 0.000030 SEK (sorry, I couln't get it in either USD or EUR). In comparisment, the 50 Cêntimos coin (shown above) is worth 0.00019 SEK.

Or let us say it like this: You'll need 3,038 of the 1 Tiyin coin to make it equal to 0.01 GBP, or 2,000 of them to make it equal to 0.01 USD.

I can't imagine how many 0's there would be if I took the then-exchange rate on some of the old Turkish Kurus coins I have.

Take your pick, any of the demonetized coins in my collection have a monetary value of $0

If the Pengö was still exchangeable...

1 Fillér 1926-1939 (1/100 pengö)
= 0.000,000,000,000,000,000,000,000,000,000,000,08 EUR

1 Fillér 1892-1914 (1/100 korona)
= 0.000,000,000,000,000,000,000,000,000,000,000,000,006,4 EUR

Quote: "Tovarich"​I can't imagine how many 0's there would be if I took the then-exchange rate on some of the old Turkish Kurus coins I have.

10 para = 1/4 kurus = 1/400,000,000 TRY
= 0.000,000,000,77 EUR

I am using the Numista database as my guideline for "demonetized", so this one can still be exchanged at the bank...

The Zimbabwean coins are probably pretty low value due to the hyper inflation they went through.

Quote: "neilithic"​The Zimbabwean coins are probably pretty low value due to the hyper inflation they went through.

​But the cent coins were used before it got out of hand, so they still had a value then.

As I am only looking for my lowest denomination and not necessarily it's value against other currency's, then it has to be a Great British quarter farthing. 3,840 to the pound
