I might be wrong, but as a long-time eBay user (buyer and seller), it seems it might be due to the seller fees going up. PayPal fees are higher, final value added fees and eBay seller fees are higher and shipping prices are significantly higher. A lot of sellers will offer "free shipping" but in reality they're bumping up the cost of the item to offset the increase in shipping.
For the last 2 years, I've been shipping some stuff to a friend in Australia. He buys stuff from eBay, sends it to me and I repackage it in flat rate boxes. The Large Priority Flat Rate Box was around $65. This week, I tried to print some postage for him and the price is up to $78 per box. That's almost a 25% increase. If I were selling him stuff and having to ship the items out of pocket (rather than him paying for all the shipping), I'd pass the cost on to the buyer.
Also, pens made 50, 60 or 70 years ago are older and older. Parts are rarer. As they break and are beyond repair, those that are left in good, working condition are increasingly more expensive because they're rare. Add the rarity to the rising cost of doing business in general, and we buyers are absorbing the added cost.

No, that's not blood. That's Noodler's Antietam.
