Not familiar with that Silver Guardian, if it's real it may only be worth melt. 1891 Morgan and the 1925 Peace are worth silver melt, $45.24 combined, or $22.62 each. A dealer offer would be between $17 - $18 each. The 1883-O is a common Morgan, and if it wasn't for the scratch at the corner of her eye, and on her cheek on the obverse side, the marks on the wing on the reverse side, it might have hit uncirculated. I would say maybe XF, possible AU, but I would need to see a clear pic of just that coin to say for certain. Value would be just slightly over melt, $25 - $30.
