The value of anything is determined by what it has sold for not by what people ask for it
Hence the DOA 5 CE for xbox is worth about 35 - 45 USD used and around 50 - 85 USD New

Again that is my opinion on it but it has rather variable past sales
Likely the difference is caused by listings with international shipping vs domestic only listings
