Various collection - could be stamps, coins, cards, tins, hardware, cars, bikes, books, cups, plates, photos etc.

Is the idea good? I couldn't find a good portal for (English) collection from Google. If any of you could find, pls share appreciated.

I accidentally found out one from China.
http://www.cangdian.com (Cang = Collection, Dian = kinda Manual)
I'm very impressed for its very informative topics, various & organisational topics, frequently updated news - out of my capability range. Admired/respected.

One of an examples about news:
The world's first stamp (UK) bid for millions.

I found out that many China portals are very richly informative (many topics and pictures for sharing).
