Hello @djohan, I think that the coins do not have value now, but collectors can buy them after many more years. Currently there is a lot of talk about keeping silver coins, it seems that they are increasing their value, good to continue with the cryptocurrencies to see what happens .
Blessings:)
thank you martha75, some of the coins are rusty now, and very small value, maybe have lost 90% of the currency value in the last 20 years, but good lesson to not save money in that form (fiat). The number written do not change, but the purchasing power have gone down a lot.
