was more thinking of the fun factor vs. good price.. A pile like that could really get someone into coins.
OK, I'll be more blunt. That seller over-grades and over-prices just about everything. I would not buy from him even if his were the ONLY auctions.
I don't know how bad it would be to buy. You might get something good. All the coins he pictures are pretty good...but not over $3000 for all of those.
I certainly wouldn't plop down all that cash for such a collection, but I sure would like to have all those world coins...
