Value
Value is for collectors who like to keep track of what they've spent. It compares the price you paid for each copy with your own estimate of what it's worth, and lists which games are worth more or less than you paid.
These numbers come from you, not from a store or a price guide, and they're shown in yen. They're private and never appear on your public shelf.
If you'd rather not see prices at all, you can switch them off in Account. The Value tab disappears until you turn it back on.
