@Zaku No; and sorry-I just now saw your question. Moroni, after directing Joseph to the plates buried in a hill conveniently located near his home, vanished. Joseph claimed he kept the plates and translated them into The Book of Mormon which took a couple of years. He said they were written in “reformed Egyptian.” But, then, he had an interest in the Egyptians. Smith purchased a mummy from a circus I believe.
Before they were taken back by Moroni, several men claimed to have either “hefted the plates” or had “seen them with my spiritual eye.” They were covered with a sheet or some sort of cloth cover when this allegedly occurred. Fearing they’d not be believed, since Smith was a well-known ‘money digger’ for years and was actually prosecuted for it, they signed affadavits saying they saw the plates. Several of them were brothers.
