Hey guys I happen to have a set of SS rims I believe for 69-70 with only minor minor rust that wont be difficult to take off, How much are they worth you guys think, and what If I take off the rust 1st??

Value is dependent on a number of factors: What condition are they in? Roundeness? Lug hole condition? Pitting? Are they painted or not? Is the paint correct? Are they a "matched set" meaning that they all have the same code and date stamp on either side of the valve stem.
Basic wheels unfinished w/ mixed codes and date stamps are worth about $50. each.
Correctly finished matched sets go for as much as $100-150 for each wheel...usually trim rings & ss center caps are part of the deal. Values also vary also based on demand and who is looking.
Good luck
