Seems like the question is going unanswered. I have seen 35-100.
Seeing there is no way these sell here, I got the 177g for 25$ and the 175g for 27$. The 177g was up for maybe an hour on ebay with 15 people watching, Buy It Now. I bought it the second I saw it because that's unusual.
The other went for a 27$ that ended at midnight, so no one was really contesting it. Also unusually low.
I think 25-40 would be a "score" to purchase ( a loss for the seller though ) 50 would be fair.
This thread and hassle is not worth the $13-20 profit on either disc. I'll just have to keep em for the bag.
earlier in the thread I said I dont "know what they are worth" because I truly don't. I'm just remembering discs from memory and what they go for in my "Ended" section
