Bueller? Bueller?

From what I have read so far, if a banknote is graded it will just get a "Details" grade with a short blurb of what damage the bill has if there is handwriting of any kind on the bill. I have the opportunity to buy a bill from someone, BUT, the bill has writing (a "75" to the right of the seal) and a red felt mark just touching the top of the 2nd last digit of the serial number and is about "2 digits' wide. Question is, HOW MUCH percentage-wise is the value of a bill (in general) reduced by pen or felt marks? So far I have only seen it described as "Significantly", but are we talking 50%... 75%... more?

I'm curious what these matching serial numbers are worth. On the one hand it seems hard to put together a pair, but on the other hand you had the BEP selling them on 3 denominations (all started with 888 due to some lucky number promotion). Is there a website that shows pricing for these? I've attached as image as an example as well as the 3-note example sold by the BEP/Feds.

It's been a while since I have been on as the website is keeping me busy. I have had several matching pairs confirmed recently. Here's just one example. Check out the site at Project 2013B

The project has now matched it's 8th pair of the year. One pair recently sold on eBay for $9300 US.
