First is a silver certificate most likely worth about 2 dollars, second is a 1943 ww2 steel wheat penny since it looks to be in mint state it should be worth around 4-5 dollars, third is a morgan dollar in very bad shape you would get between spot value which is around 16 dollars up to 25 dollar if you put it on ebay, fourth is a german nazi coin made out of zinc worth around 1-2 dollars, last in a british large cent in horrible shape probably only worth about a .10 to the right person
Welcome to the forum Smokey. What they are talking about is that in the 50s and 60s , it was common to replate the 1943 (P,D,S) with zinc to make it appear to be uncirculated and shiney. Since it was the responsibility of the collector to clean them before sending them in, they were processed with crud on the coin and it could produce small bubbles under the zinc. Since replating process covers all of the coin and not just the top and bottom as original was , replating also plated the edge of the coin with zinc. So if you can't see the steel center and it all appears zinc, it is replated and worth little compared to an uncirculated re-plated one.
