I think the first is the 'orange peel' affect, however im not sure what this means or how it happens. This one resembles a broadstrike i believe but not as apparent. there is no rim.not sure what it is. This one has a really strange raised rim on both sides. its almost sharp. and before you say squeeze job, its circumference is slightly larger than a normal penny's. And if you're still reading, what causes this? i have several of them. <next post>
On your last coin posted (1943 steel cent?) I believe is a coin which was struck on an improper alloy mix blank or planchet. This is a coin struck on a blank or planchet made from a coin metal alloy which was defective because of a failure to properly process, heat, or mix the metals, or defective by adding the wrong metals or omitting metals before pouring the ingot, showing on the struck coin as mottled or streaked metal. Keep in mind that the color of any coin can be altered with an acid-base cleaner to give it the appearance of being Improper alloy mix blank or planchet. Also it is not considered a minting variety/error (at least to me). The first coin, seems to me to be as close as a coin struck on a foreign-stock planchet or something like that. You would have to weigh and measure its thickness to be sure. The other two are just questionable to me because what looks to be a capped die, shows on both sides and I don't think that's possible. Basically, I'm clueless on those.
