I have trouble parting with them , your offer though is far more than I think they are worth.
I will keep a watch out for you and if I happen to come across extras at some point they would come
to you at fair price. They all are toughies but the market is very shallow , the $25's are probably worth
$50 on a good day and the $3 drop chip likely $10-$20.

If anyone has any of these which I believe there may be a few out there there likely will never be a better time
to cash in.

May Lady Luck assist you in your hunt!
