Downloading the data via CSV is the way you download the checklists.

You can do it by console if you want.  On the set page, there is a "Download Price List" link right above the item list.  You can click that and download all the items for that set only.

You can then filter that list.  

Release Date is only included in the download in the Legendary tier (along with other item meta data fields)

Cool idea.  That would be another cool way to value a collection of gold and silver coins.

Sorry for any problem. I've asked servers to revalue and recount everything. That should be done by the time you get this. Sorry for any inconvenience.

Sorry, we do not track different region versions of these items at this time.
