Had to reset the sharpness of my computer imaging in order to view your pics. Background was interfering with the view.
Looks like 2 ea 5/8" 18 gu Brad point nails for use in a pneumatic or electric brad point nailer and 2 ea 3/4" 21 or 22 gu copper headless pin nails for use in a pneumatic or electric finish nailer. Both nails used for finished nailing in wood surfaces where the appearance of nail spots are least desirable and the nails used are undetectable after filling and putting before final clear coat finishing.
