Yeah, and to be fair, finding a commander's arsenal foil in the Nm/Lp range will probably be a bit more difficult than this Sylvan Library, considering most people probably bought them sealed and tossed it in a dark closet or something.
Also considering how different the foilings are, I assume the reprinted Library will appeal more as you stated as well.
-----(some background if you wanted to know)----
(Sorry for a long story, but this is how I became an "official" investor of MTG)
To be fair, I started collecting Libraries around GP Vegas of 2015, when Star City Games and CFB, in their Played/Heavily Played section, both had a stack of Libraries for $3 (no tax) (I believe the libraries averaged about $20 or so TCGMid for NM at the time) and I had a real laugh in my head saying "even if these are beat up, I guarentee somebody would at least buy this for $5 for commander or something"
So, being an "investor" (at the time I couldn't take MTG Investing seriously, I thought it was a joke or a heavily played inside joke), I bought around 120 copies (mostly fourth, some fifth, and a few Legends (yeah, a played legends for $3? Sign me up.) So I began buying all of them everytime I went to a GP, and soon I had a stack of about 500 or so from casually enjoying events. (Given they were considered "played or worse", but many of them only had slight wear around the edges, stuff I would consider LP-/Played+)
So when it got reprinted, I was really bummed out (but then again, only in about $3 a card... so how can I be mad?), but then I told myself to "double down" and bought any Libaries that went around 8-12, give or take. I bought all the foils around 25 or so from LGSes and local people because the Commander/Legacy/Eternal scene is dead, it's all standard/sealed/draft where I live so I ended up getting decent on foils since everybody was opening it up for "money cards" that nobody really used. (Also, low key an LGS near me 'convinced' new players that Eternal Masters/Modern Masters etc... would be in 'standard', because LGSes have a tough time in my parts for selling product like this and decided to be scummy about it....) so an abnormally high volume of product was being consumed of EMA/MM2 that was mever sold, so I basically picked through it as people opened it since I was the only one that had uses for it.
But I do regret buying so many, as IDK how to get rid of them without dumping them in a buylist:
Current Inventory: (haven't inventoried them based on wear, but assume: 40% is NM/LP, 50% Played (no hard creases/rips/tears), 10% damaged (no rips and tears, but small creases and etc)
Commanders: 0 (to be fair, I thought they looked like garbage) 4th: around 400 5th: around 80 Legends: around 25 EMA: about 120 EMA Foils: about 20
I've honesty just bought a binder and just stuck them in there and never really touched them haha.
I basically invested in them on 3 things: 1) it's Harold McNeal, so I assume we won't be seeing him as an MTG Artist, so I was betting more on the "art" of nostalgia. 2) It's probably one of the most unique (if not the most unique) Green Cards that will probably ever exist in terms of Draw Power. 3) while not RL, I wanted to "invest" in a card that was resilient to reprints, as in even if it got reprinted a few times, it would level out within 6/12 months and just be a staple.
While certainly my most vast collection of investments, my most profitable one has been Mana Crypt (i bought a whole bunch at 60-80$).
