Any help with authenticity of these Coach bags that I have purchased in the past is greatly appreciated

Thank you in advance!
1. Item Name : 61B-8751 - Not sure of the name of the bag

Comments: Says Made in USA on the bottom. Did bags ever say "made in USA" or has it always been "United States"?
2. indicates made in 2001. Should the country of origin be stated in the creed and did not on the bottom of the creed?
2. Item Name:City Bag

Comments: Zip pocket on front rather than on the back wall of the bag.
Creed has Made in the United States on the bottom versus in the second sentence ~ (one example of a bag I have made in 1994 with the Made in United States at the creed bottom) .
I've been learning so much that it's been fun and challenging to go through all of the bags that I have. I'm hoping these are authentic but these are the bags that raised some flags for me. Thank you so much for your help!
