I'm hoping someone can give me an idea of what to do with this ingot I recently purchased from a Facebook marketplace post. Quick backstory before someone jumps on me for paying $1/pound. Sourcing lead in Middle Georgia has gotten very tough. Most tire stores are now selling wheel weights for $40/bucket and the percentage of actual lead weights is somewhere in the 30-40% range at best. That being said I've moved to buy pure lead where I can to also save the hassle of sorting through a large number of weights.
I picked up this ingot for $100 and it weighs just a tad over 100 pounds. In doing a little research to verify the composition I've discovered this may be a very old ingot. I've found a few articles on Thomas Selby and the company which apparently was acquired somewhere around 1905.
Here is my question... is there enough either cash or historical value for this ingot to not melt it down for casting. I've found that Grade C is 99.9% pure. I've found the one on eBay for $850 and the one that was sold at an auction for $1200. Is this one possibly worth a proportionately similar amount?
