My condolences for your loss but also, my greetings from Helsinki, Finland! Welcome to FPN!
What a nice collection of pens and in mint state, not something you see every day...
The Pelikans you posted are (from the top):
Pelikan ? > Don't know which model, a later one from the 60s?
Pelikan 400NN (with the box).
Very nice! Those should be good to go as is (just fill with ink and start writing). Also, they are very fine pens as writers (Pelikans of that era are the focus of my personal collection and everyday users, carry a few with me daily to write with). I just love them to bits. <3
They are not ridiculously expensive (YMMV though) but as everyday users and writers they are just plain awesome. Great ergonomics, nibs, design, ink capacity etc.
The smaller 140 is about 75€ to 100€ or more depending on the nib and color scheme, the 400NN can be found for 90€ or more in mint condition, same applies to special nibs and color schemes (prices for Europe can be observed on ebay.de etc.). Prices from professional vendors and outside of EU are naturally higher.
Oh, one thing to be aware of, wider nibs, esp. oblique ones are more rare and desired as are the more rare color schemes (green striated is the basic model, black pens are more rare as are "tortoise" or honey/brown striated etc.).
What is that bag of nibs with the Soennecken pens?
Also, loads of other nice pens (the Parker 51 set is especially nice). If the Parker 51 is an Aerometric model it is also "good to go" with just a flush and a fill of ink (another favorite of mine).
You have a great collection of pens there and I would recommend taking the time to get to know them, as in, write with them and see what you personally like and do not like. Each one of those is more or less an individual with certain characteristics shared within the family/brand. Thinking of the adventures and discoveries waiting you makes me smile.
