There are many variables / factors that determine the value of something, in particular when it comes to classic computer (parts). It's not just condition, but also how complete something is, how desirable an item is (think of its features and/or its rarity), where it is being offered (thrift shop, ebay), who it offers (think of feedback, related items), whether any warranty applies, whether shipping is an option, maybe a story / history behind an item, economical value that an item may still have etc. All these factors make it quite impossible to compose a proper price guideline.
I have paid almost pennies for some things that are being considered very valuable by some and paid astronomical sums considered by some for not so special items. In the end we are looking at things that are not mass produced anymore, many that have no economical value anymore, so it's really whatever someone is willing to pay it.
