The search functionality seems to have degraded. When clicking on a 'Country' it used to return that countries list of coins - now it just says 'not shown' as shown in the image below...
If I go to the 'search' function and look for a particular coin e.g. United States 1 cent - it brings back a few pre- federal and exonumia / token items, but not current USA. Similar issues for other countries.
When you click Advance, then Coin Type, "Multiple (3)" shows up. What is that. Of course you can then click "All" but it looks as if you would have to do that for each country, all 400+.
