If I've got the orientation correct on your first one i can make out AELFG. That i presume is part of the moneyers name.
Going through my books the only one i get a close match with to that is Aelfgaet at Sandwich mint. But do not take this as 100% accurate. I'd need a clearer image to positively confirm that. I am 100% sure your bottom one reads ULF ON LINCOLNE.
