The ability to see ones collection history for individual collections

I saw that when selecting a specific collection, we can see the years, for that specific collection, but not the collection history. The collection history is for the whole profile.

I'll like to suggest we can see a specific collection, with that specific history, like with the years. If that make sense? Like with here. I've put my collection to only show my Euro-collection, but the history is for all my coins.

That would be nearly impossible to do, as you can move a coin from one collection to the other. It would become a mess...

But smvdbrink, we have that with years:

So I don't really see, how that is different? I don't know anything about computers or programming, but it seems to me, to be the same gemick needed..?

With the years I can see all my collections at once, and I can select one collection, eg. Euros, but the collection history is only for my combined collections, no matter what. If that made sense?

​I understand your logic, but the cases are really different. With the years, it's quite simple. You take all the coins in a collection and you sort them by date. If a coin goes from one collection to the other, it just goes along in the count.

What you are asking, if I understand you correctly, is to see the grow rate of a collection. Right now this is done over your entire collection and therefor you only need the datecreated of the coin. With your request, a changelog of the coin needs to be implemented, keeping track of when a coin goes in and out a collection. That requires quite a lot of programming for a really small feature. Also, it will most likely slow down the homepage and I think that's not something we should want.

You can track your collection changes here, but up to 6 months back, I think:
