I saw a demonstration of MA-Shops at NYINC today. It is a European competitor to VCoins. Supposedly there are 120,000 items for sale on it already. I see 1350 ancient Greek coins, 3082 Romans, and 213 Byzantine. 922 Medieval. A lot of modern coins, especially German. About 500 numismatic books.
I like MA-Shops' ability to view by category. I think that's better than VCoins, which has per-store categories but no overall. The downside of MA-Shops is the search functions. It doesn't support wildcard searching (*). It doesn't support automatic synonym searching. Those features what makes VCoins great, and they are needed even more on MA-Shops because a lot of the descriptive text on the site isn't in English. This means a lot of searching for the same term in various languages.
