Ok ... I see where the confusion lies. When you enter donations the current fair market value you would see at a thrift store is usually the amount you list and that amount is usually lower than the price you actually paid for the items originally. If you are using the current replacement price for that vintage toy (what you could sell it on ebay for) then it is very possible you donated items with an appreciated value if they are vintage and in short supply. Most toys that are not in the original packaging untouched by little hands will not appreciate in value.
So the FMV you will enter is what your local thrift store may get for the item if you donated it to them.
