How do I search for coins to swap that I am interested in? [επιλυμένο]

I am looking for a number of coins including a 1799 coin.   Anyone know how to search 1799 coins?

THESE are all the coin types that contain a coin that has a written year 1799. (Filter: Available for swap: yes)

But this doesn't mean that a coin with the year 1799 is offered for swap, it is at the moment not possible to search for specific years that are offered for swap. So you have to look through the types and see if a 1799 one is offered under Get this coin » See the details of the coins available for swap or you know what type you want which would reduce the number of pages if any are left. 

This 1799 3 Pfennig coin is offered by 2 members for example

N#19033 

Thank you very much for the clear explaination
