Wizards aren't really overpowered in the beginning unless they play their cards right.

Example Spell - Prestidigitation: Can create a Trinket for 1 hour. This trinket can be a ball of feredium.

The trinkets created by Prestidigitation can't deal damage, so I don't think whatever "feredium" is would make a Wizard overpowered.

I'm voting no. Being "OP" is a very context-reliant thing. Generally, no class is OP in normal play.

If a wizard is high enough level with lots of time for preparing and the funds - they are the most powerful class in D&D. They can create infinite armies, become immortal, acquire infinite wealth and many amazing things. However, that is not really something a player is going to do. In terms of going on adventures they are not OP. In terms of PVP they're not OP. No class is.

This is a very weird example. 

I don't know what feredium is, and when I try to google there's no real definitive result - closest is a syrupy ingredient in eye drops. Based on context I assume that's not what you're going for. By 2014 rules a trinket is a "simple item lightly touched by mystery" so you're not creating radioactive rods or unstable chemicals - these are not "simple". 2024 rules in the spell state the trinket you create "can deal no damage and has no monetary worth". Anything that can be used dangerously would fail both requirements. Conjuring weird chemicals for odd reactions and such things would also require heavy DM involvement and there's actually stuff in the new DMG to disallow such things because D&D worlds are based in Magic not Physics. Things exist because of magical nature not due to atoms and molecules. 

Your example is also weird because Prestidigitation isn't an exclusive Wizard spell. It's also for Bards, Sorcerers, Artificers and Warlocks. It can also be taken by 2014 High Elves and High Half-Elves, it can be taken by various subclasses like Arcane Trickster Rogues, Eldritch Knight Fighters, Arcana Domain Clerics - and more. There's also feats, such as Magic Initiate, that can let any character gain it. So given that basically any character can gain, or even start with, the cantrip I'm not sure why is an argument for Wizards, specifically, being OP? 

Op compared to what? Compared to my homebrew class GOD that forces you to make a do 10000 Intelligence check or take 700000000000 d20 da,abe then no. But seriously it is probably 3rd most powerful class or maybe 2nd.

No idea what fededium is (doens't come up on a search), but if it has a monetary value, it can't be created as trinket.

"Minor Creation. You create a nonmagical trinket or an illusory image that can fit in your hand. It lasts until the end of your next turn. A trinket can deal no damage and has no monetary worth."

OP is relative. Pick a strong 2024 subclass from various full caster classes, make good choices, and play it well, maybe even creatively...and people will think you're OP. Im not even talking about multiclass. I was told my character was OP as a Stars Druid (I disagreed). You can do that with various classes/subclasses, especially full spellcasting classes. You can certainly do that with wizard if you build it well.
