So as you are new, here are four screen images that may help ...
- 1 On top left of most pages is The catalogue
where the Country list and the Search are found
- 2 Not sure what coins you have, so I chose, from the Country list, Albania as an example
- 3 Then if you wanted to find 1988 coins from there, type in the Keywords box, then click Search
- 4 Using, as an example again, the 1 Lek coin from that search, here is what a page looks like. On there are the five coin grades VG F VF XF UNC and you type a number in the box (so the - is replaced) if you have coins in your collection. Or if you have some for Exchange, put a number in the sixth box. You can make your own notes about the coins by clicking in the Personal comment? box also.
Just above there are two boxes - you can tick in I wish to get this coin if you do not have one but need it for your collection, or tick the second box I don't wish to get this coin if you do not need one. Then either a red heart
or a grey cross will appear against that coin for future reference. Which will be handy for any swaps you might make in the future - but that is for a later date!
All those mentioned above are what most members are used to doing, but like you said if you are brand new here it is a lot to learn. Let me know if you have other queries, and there is a Topic created a week ago that has other answers on also (further down the page) ...

If you did want to see a Swap page, see my reply - Posted: 22-Jun-2012, 07:18PM
on that Topic; there is a screen image of the hearts and crosses mentioned, so you can see their purpose to help make swap choices easier.
