Hi, any help with authenticating these four bags is appreciated

With all that I've learned, they look good to me but I want to be sure for selling

thankyou!
Quick question: some bags that I'd like authenticated I'd also like ID'd. Do I post them both here and in the ID section?
1. Item Name: sheridan Bag, not sure of the style

Comments:This looks to be a Sheridan style, like the Glenwood 4225 Hyacinth recently identified of mine. It's a bit smaller, measuring 9" length, 8" height, and approx 3.5" deep. This one doesn't have a serial number, as indicative of many Sheridans and Dakotas. I just want to be sure it's authentic.
