1) The 2-digit 5$ bill would be worth around 25 to 35 bucks to the right buyer based only on the serial number. If it's a rare block or short print run it might bring that, or more, to a buyer looking for that particular series
2). The near-solid serial number C note is just that, a near miss. I'd estimate somewhere around 150$ on it.
3). The repeater 20$ note is in my opinion is your best note. 50 to 100$ to the right buyer.
Others will have different opinions as to values. Goes with the territory.
Please, next time post only one note per thread. It keeps the thread from getting confusing as more replies show up.
Nice assortment. The 2-digit $5 replacement note is worth a minimum of $150, maybe more. The $100 note with seven-of-a-kind last sold for $218 in 2010, and I don't see much change. The 1996 $20 Super Repeater last sold for $246 in 2013, and once again, I don't see much of a change in price.
