The current exchange rate is <38¢ US to the Suriname dollar. If you have enough to make the exchange worthwhile try visiting the currency exchange booth at your nearest international airport - probably run by Thomas Cook, Inc. Your own bank probably has a correspondent bank that handles currency exchanges, but most banks charge a service fee in addition to giving a lower exchange rate than the published one, which is generally applicable to large inter-bank transactions. BTW you only need to post a question once.
You may do better selling the Suriname notes on eBay (especially if they are in good condition and attractive) rather than converting them at a bank or currency exchange. I exchanged 1000 Dutch Euros a few years ago (when the dollar and euro were 1:1) and Chase Manhattan charged me an arm and a leg to convert them to dollars. If I had merely held on to them I would have made $500. :hammer: Even with eBay and PayPal fees you'll only have to pay an arm and you'll get to keep the leg.
This is more true than you think, when I came back from Iraq I had about 300 USD with of Iraqi Dinar. I was going to hold on to it, but after a couple of years I got impatient and nobody wanted to exchange them (due to being unstable). So I posted the whole lot on eBay and sold the lot for 375 when they were only worth 300 and I couldnt exchange them. So, eBay is a VERY easy way to "exchange" your currency.
Especially because the initial poster asked about gulden, not dollars. The country used the Suriname Gulden/Guilder until the end of 2003; on 1-Jan-2004 they replaced it with the Suriname Dollar, at a rate of 1000 SRG = 1 SRD. Christian
Suriname, the only country in in the Western Hemisphere that speaks Dutch that isn't still held by the Kingdom of the Netherlands. Currently 1 Suriname Dollar is worth about US $0.37... and 1 Suriname Guilder is worth 1/1000 of that... so basically unless you have a ton of them Suriname Gulden banknotes are nominally next to worthless. You'd get a lot more selling them to collectors than converting them. Suriname does produce nice banknotes: 2 1/2 gulden, 1985 10 gulden, 1963 I'm sure you can find a collector on eBay or somewhere else that would buy them off of you, especially if they're in decent condition.
