RE: Some LDS will say that they literally saw them, others will say that they saw them “spiritually”.
Not true, the witnesses testified that they literally saw the gold plates.
Here’s a quote from Martin Harris, one of the three witnesses:
When asked, “Are you sure you saw the angel and the records of the Book of Mormon in the form of gold plates?” Martin Harris replied, “Gentlemen,” and he held out his right hand, “do you see that hand? Are you sure you see it? Or are your eyes playing you a trick or something? No. Well as sure as you see my hand so sure did I see the angel and the plates. Brethren, I know I saw and heard these things, and the Lord knows I know these things of which I have spoken are true” (Deseret News, 2 October 1943, 6).
The eight witnesses also testified that they physically saw the plates, handled the plates and turned the pages.
BE IT KNOWN unto all nations, kindreds, tongues, and people, unto whom this work shall come: That Joseph Smith, Jun., the translator of this work, has shown unto us the plates of which hath been spoken, which have the appearance of gold; and as many of the leaves as the said Smith has translated we did handle with our hands; and we also saw the engravings thereon, all of which has the appearance of ancient work, and of curious workmanship. And this we bear record with words of soberness, that the said Smith has shown unto us, for we have seen and hefted, and know of a surety that the said Smith has got the plates of which we have spoken. And we give our names unto the world, to witness unto the world that which we have seen. And we lie not, God bearing witness of it.
Two other interesting witnesses were women: Marry Whitmer and Emma Smith.
So you have at least 13 people that physically saw the plates, not one of which ever recanted their testimony. Some had disagreements with Joseph Smith over church policy and later left the church, but amazingly all continued to testify that the plates were real and the Book of Mormon what exactly what it purported to be.
