Ask/Bid For 1852 $1 Gold

I saw a coin I really like today, and rather than wait for payday and risk it walking out with someone else, I'm thinking I might take the above coin, ANACS graded AU55 in. My coin is worth more, but I had planned to trade that one up when I saw something I liked better. I'm pretty sure I paid a bit less than book for it, so I think I should recover what I paid. (I could also take in a few more modest coins that I picked up just to establish a relationship with dealers I liked, but I'm pretty sure I paid book or a bit more for them, and I thought I'd hang onto them until silver goes up and see if I could recoup more of what I paid--feel free to tell me if I'm thinking wrong on this).

Does anybody have a Gray Sheet, and can you tell me what the ask/bid is for that coin and grade?

Also, when you bring a coin worth more than what they're asking for the coin you want, do dealers usually give the rest in cash or ask you to pick other coins to even the trade? I saw one other coin in the store I kind of like, but I really don't need both.

Thanks!!
