My grandma gifted these to me several years back but I never really looked at them, I just put them away. They were stored pretty poorly, some of them have rusted and I don't know if it was there from the start or was it from how I stored them. These denominations are worthless to spend now.


These are 10 and 5 Rupiah from 1979, all aluminium.


These are bigger coins from 1970, 1971 and 1974. I'm not sure what the 25 Rupiah is made of, maybe cupro-nickel, but the rest is aluminium.


1974 5 Rupiah coins. They appear tombac, I don't know why they made 2 versions of it in the same year. It's also smaller, about 3/4 of the aluminium one's diameter.


Here are the crown jewels, Nederlands Indische coins! The interesting thing is they are in coin orientation, Indonesian coins have medallic orientation. There are 1/4 Gulden from 1915, 1941 and 1945, 1 Gulden from 1943, and 2 1/2 Cent (sen?) from 1945. I'm sure the 1/4 Gulden is silver because it is whiter and I think the 1 Gulden is also silver (from its mass, you can feel it's denser just by picking it up) but I can't tell for sure due to its colour.


There is also a roll of what appears to be rusty 1/4 Gulden coins, but the amount of sellotape on it (and the fact that they look pretty bad) kind of puts me off.
