Based on the images provided, here is my opinion.
1933. No visible error.
1941D. Laminate separation. Possibly post mint.
Reverse shown has relatively recent damage. No error noted.
1948S. Old damage or corrosion on collar. Image too poor to make and qualified judgement.
All images appear to have been taken by a hand held device. If you are going to take a lot of close up images, please use a quality mount for your camera or smartphone, such as a sturdy tripod. The images will be much better, with detail easily discernible.
Time for more coffee.
