Good luck! Hopefully you'll get some 40%ers at least.
I've ordered 2 1k bags of ikes before and found 4 40%ers. I sold them in lots of 100 on ebay for min $125 + Shipping. So profit of $9 per 100.. (I'll take 9% all day) but it took a while to sell 2k worth..
I would grab handfuls and do quick edge checks as they are huge and any silver peace Morgan's or Ike's will be easily seen. Then I would start checking for errors.
I've sold Ikes by the $500 batch for $1.08 per coin. Not a lot of profit, but when I order $1,000 I either get some silver dollars (Have gotten both Morgan and Peace in the bags) or I sell them for $1,080, which is still an $80 profit for less than an hour's work. I can't get them often, but when the banks have them built up to a full bag (Yes they are $1,000 bags, not $500) they will give them to me. Always worth the effort. :-)
Those bags are almost as cool as the Ikes. I've snagged a few cool mint bags over the years: official US Mint cents, dimes and quarters bags. I think they are property of US govt.
