Question on a price

I asked Clint as well but thought I would see what other's think. I have some baggie figure's up for auction on eBay one being a 1977 Han Solo I started the bidding at $300 with a guy messaging me asking if I would do a buy it now. My issue is I don't know what it would be worth. I was thinking maybe $500?  Here are some photos.

Any help would be appreciated.

I can only find some baggies on eBay going for about $350 CND.
Try letting the few auctions you have running to the end and see how it goes, before listing more.

edit.
According to Frank's page over on SWFUK.  It looks to be a SW-b or SW-d bag. Similar to the link that James posted.

Kind of hard to nail down a definite price but here's the only completed listing I found on ebay for a baggie that looks like it is the same version as yours : [You must be registered and logged in to see this link.]

I saw other various bags sell in the $175 to $250 range (US Dollars) .

I think your starting price for the Han is pretty close - like Clint said , just let the auction run and see where it ends up

That sounds good to me, thanks guy's. I find the baggie one's a lot harder to price then the carded for sure.

Yeah I did a quick search on ebay and average price seems to be between £150 - £200.
£150 pound sterling roughly equates to $250 CND
So like the other guys said, I think you're pretty accurate with your listing price
