$10 per gram would be $170,000. As larger meteorites go for more per gram, it would possibly go for $50 per gram, which would $850,000.
I would not expect it to go for more, because it is not flashy or obviously, visually, meteoric.
But large, intact meteorites such as this are very rare. An auction would determine the real value.
The above is based on a few minutes researching the subject on the internet.
Antiques Roadshow says that it would be worth a whole lot more if it didn’t have that slice taken out of it…
