This will be a running list while I work to compile the whole thing. If you have some of the low level item prices please help me fill in the blanks.
All items will be in order from left to right starting at the top with coin values to the right of them. I did miss some of the early items and will try to get their values.
The achievement popped for me at about 775,000 coins collected (and spent) for reference.
Total - 33,100
