I’m a total noob, so forgive me if this a dumb question or in the wrong forum.
This 1934S peace dollar is being sold as graded AU58, does this seem like it’s been graded too high and possibly tampered with? 
It’s been graded by a company called UCGS, anybody familiar with them?
My gut is telling me not to purchase this and I think I’m just looking for someone to tell me I’m making a good choice. 
Thank you for your time.

Universal Coin Grading Service. Don't know much about them. Is the price right? Doesn't look AU58 to me, but I am not a professional grader. If the price is a bargain, then why not. I personally when buying a graded coin would stick with NGC, PCGS, and ANACS. But if it's a bargain price, then I might go for it !

I completely agree, this is a total rip off. No way that is an AU58, and the only reliable grading companies is the NGC, PCGS, ICG, and ANACS. Don't worry, it isn't a dumb question. We all started collecting at some point, and most of us at that point won't know everything about the different certification services

Also, it appears that you are a new member. If so, then welcome to the ANA!

There is absolutely no way that that coin is AU, maybe XF at the best.

And ya, welcome to the ANA!

It's a scam Use the services most are use to PCGS  or NGC or.ANACS.. Those are the top three. Never heard of the other one. Welcome.!!!

Yeah, I dont trust it one bit.  Looks cleaned to me as well.

i say it is about VG-4

Without a doubt way over graded, even with the less than optimal photos. An au would show no wear on the eagle's head, the wings would be well defined. On the obverse, the hair detail near the forehead would not be worn smooth. Another one of those so called grading companies peddling over-graded coins. A fine at best. If it is genuine. A true AU58 sells conservatively in the 350-400 range.
