If you’re looking to buy these, maybe you should post it in the Buy-Sell-Trade area of the forum.
They are not hard to find but are very popular, so you probably won't find them discounted much by sellers.
You might want to indicate if you are interested in lower or higher circulated grades or both. No folds or tears indicates that you are looking for circulated notes but the two that you picture appear uncirculated. Be specific as to grades of interest.
As I said, there are plenty to choose from but few bargains available due to popularity.
Ebay has a Bison without tears, folds, etc
Where were you when I was seeling a nice Bison at 64EPQ ?
