Value On Large Slag?

[Al Oregon]

Our local Museum has part of my collection for a couple months (rotating local collections) and I spent some time yesterday looking at folks' marbles and telling them what they have. This large amber slag came rolling in and I really had no idea on value so I snapped a couple pics and told them I'd ask on the boards. It is 1 & 27/32 inches in size and there is one tiny chip (didn't show up in pics that I took). I assume it is MFC. I'd like to give them a rough value range if they should sell it. Thanks for any help.

I once sold one just a hair under 2 inches with a few moons for 350

Al:

I have sold one in that size for as low as $35 on Ebay . Prices may be a little higher but not in the range Galen quoted. My guess is $60-75.

Sorry about that Don, Let me know if you get any more that large or larger close or mint and I will at least double your number

Thanks all. I passed the basic info on to the gentleman and found out that I was wrong in my assumption that he wanted to sell it now. It's a family thing so, for now, he plans to keep it.

A giant MFC is a wonderful heirloom. I trust you shared the importance of the marble in the history of American marble making.
