Anyone familiar with this token ? Any help would be appreciated. I know it is hard to make out in the phots but it looks like the front say NBM Co and near the rim at about the 2 o'clock position it looks like the word manufact?. The back looks like between the 10 o'clock and 2 0'clock position might be good for and it looks like trade at the bottom . In the recess in the upper middle it looks like 5 c. I found this today in a civil war camp, not that that makes it period. I hate to over clean it. 
Thanks
Larry
