Rare Civil War .577 SHALER three piece bullet - dug MM#523

Here's a rare dug .577 caliber Shaler three piece minie bullet. The bottom two are together as one, with the top unattached. I just acquired an estate collection of all different mostly dug Civil War bullets and cartridges (about 60) and will be listing them here on eBay soon. I don't know where any of these had been retrieved from as there were no notations for such - just identified according to the McKee-Mason book on the subject. Ships in a small priority mail box.

Thanks for looking and even more for buying!
