Hello, Ive been looking around for a good place to buy in bulk. Im interested in buying either bags of unsearched Wheaties or bags of Mercury Dimes. Im selling off some loose ends of my collection on Ebay and have been looking at some of the auctions for coins in larger quantitys. Theres alot of auctions for 5000 count bags of wheaties, and Ive only seen one guy who sells 10,000 count bags, which have been going for around $375 with the shipping. But Ive been having a hard time finding bulk lots of just Mercurys. Im interested in prob $100 face value bags or maybe even $200 bags. Which Im not finding on Ebay, its mostly mixed silver when you get to lots like that. And everywhere else Ive looked, all I can find is $1,000 face value bags, which is too rich for my blood. Also, if anyone knows, what kinda of prices should I be paying for say the $100 face value bags of Mercurys??? Ive never bought in such quantities, and the only reason Im able to now, is because Im selling off some of my collection to liquidate funds. Im 22 years old, and really cant afford to get ripped off. If I do things right this first time, maybe I can liquidate my assets and reinvest for a bigger turnaround. Also, does anyone have any advice for me, I have a rather large collection that Im thinking about selling off to have some money to play with. Is it a bad Idea for me to sell most of what I have and invest in bags of only Mercurys??? Has anyone else bought big bags of mercurys, what can I expect, will I end up with only cull coins of common dates??? Im nervous Im doing something stupid and any advice or past experiences would be greatly appreciated. Oh and so you know, the collection I have now is alittle bit of everything and I could prob sell it for close to $50,000
Thanks,
