✅ SOLVED Can you help? What are these?

The first one is large like a silver dollar and from 1828. The second one is nickel size and from 1869. The third one is frosted...not painted...and is clad but it just looks funny and the bank sorter rejects it. Sorry for the poor pictures but I'm not good at photography.

The nickle sized one in the middle is a British half penny. The 1971 Half dollar is a cupro-nickle with nickle cladding and is worth about .75 cents.

Thanks for the info...the half weighs 9.1g but it should weigh 11.34...I don't get it.
