Beaded Buckskin Bag

I fell in love with this bag at an antique store and had to have it. I don't know much about beaded bags or Native American work, this appears to be old, the buckskin is in great shape but the satin/silk lining shows age as it is wearing thin. The beads are colored metal. The design is similar to an Iroquois snowflake design. If anyone knows anything about such things please let me know. Thank you!
