I am into paper money collection for countries I have visited. I was able to do so prior to the implementation of the Euro.
I am visiting Greece, Croatia, Bosnia & Herzegovina, Italy, & Spain in the next few months. So I am looking for a drachma, kuna, lira, dinar(?) & peseta respectively.
Can someone direct me on how and where can I go about it? I only need one for each country, any denomination will do. Thank you

Ask Google, it will give an answer like this one for any currency:

Old French francs (coins and banknotes) can be purchased through
online numismatic dealers, auction sites, and specialized currency exchange services. Key sources include eBay, BullionByPost (for gold coins), and Banknote World for paper money. For physical shops, collectors often visit specialized dealers near the Bourse or markets like Saint Ouen in Paris.

There are shops selling old coins etc.

You sometimes see stuff being sold at open air markets

You might see some in an antique shop

I assume you know the value of what you're looking for because non of these will be charging face value

Send me a pre-paid mailing envelope and I will send you all of the pre-euro coins/paper I have at home!

Maybe too late for you for this year, and possibly bigger than you need, but there is a big coin and banknote fair in Berlin every year. It is called the World Money Fair and this year it is from 29 - 31 January. If you miss out this year, maybe next year?

Thinking on this again, in our city the stamp and coin dealers have a regular fair once every 4 months. Perhaps you could visit one of these in your world - you don't have to go to Berlin - and just let the dealers know what you are looking for. Sometimes it doesn't take legwork, you might be able to source your currency close to home! Or ask your hotel where there is a stamp and coin dealer in the cities you are going to, since you are travelling overseas soon. In our hotel in Cologne (CityClass Alter Markt) there was a coin dealer just next door.

really? i only need the ones listed on my original post though

Bosnia & Herzegovina does not use Euro, they use their own currency (mark.) In Croatia just ask around, they just switched a few years ago and many people still have kuna they found in a drawer and don’t mind getting rid of. Strike up a conversation with your barman. If nothing else, an interesting conversation might ensue.

I'm happy to send what I have. I am away from home until the end of April, but I can look at my stash then, if it's not too late.
I'm sure I would have coins from Italy and Spain, and maybe drachma.

You won't get a better deal than what ekscrunchy has offered you!

If you prefer to spend money to get money check eBay.

i wont be visiting until 3rd or 4th quarter this year

I probably have several thousand in pre-euro currency just sitting in a drawer. Happy to sell them to you.
