What is the best way to sell modern foreign coins?

I bought some lots of coins in a local auction and many of them are foreign modern coins from all over the world, I know they arnt worth a lot and I wouldn't have bought just the modern stuff but now that I have them I don't want to just put them in a drawer. 

       I saw there is a company “leftover currency” in England that will exchange foreign coins but it would be expensive to send them in from the US and I haven't seen a currency exchange in the US that will exchange coins, Another suggestion was to wait till I have enough and sell them on eBay.  

      Im not worried about the cost of my time and Id like to get something for them if I can. Does anyone have a suggestion on what to do with them since I'm sure I will keep getting these coins.

If any are Unc you need to be careful in disposing of them since Numista lists all moderns at a fraction of their real value.  

If you're just talking poundage the postage costs will eat up most of the sale price.   Legal tender coin should be saleable for 50 to 80% of exchange value though buyers are harder to find now days.  I used to send coins with friends traveling abroad to cash in coin.  Most of them said it was very convenient to have change since other countries have higher denominations which are useful in vending machines.  

Good luck.  

Make a list and see if anyone wants to swap with you, occasionally some of us buy coins if we have no swaps but it’s generally frowned upon on numista, however certain other collectors sites have a selling feature 

have you looked in to selling on ebay? I sold hundreds of things on there. 

there are other sites too, bonanza and ebid to name a few.
