Thanks for the vote of confidence, but it's pretty much misplaced. I'm basically a novice when it comes to coinage of the Shogunate.
However, bearing in mind that these are cast, not struck, I don't see any red flags about authenticity.
The loose ones (bottom pictures upside down) and the silver one in a 2x2 all appear to be Ichi-bu Gin (silver 1 bu) but I'm not sure of the precise variety or date within the period 1837-1869.
Your description of the gold piece has me puzzled. It looks like an Ichi-bu Kin (gold 1 bu), but I can't find any information on a 3g piece. The closest are 3.25g cast from 1736-1818, 3.27g cast from 1819-29, 2.8g cast from 1837-58.
I'm a total novice with these so it would take too long for me to pore through the book right now. I may be able to give it a look up over the next few days, but it's nearly 7 am on Christmas morning for me so I expect to be busy shortly

I had forgotten that Hartil discusses the rectangular coins as well as the Chinese-style cash coins.
I'm no longer puzzled about the gold coin.
It's Hartil 8.31, 3g of .229 gold. The Edo (Tokyo) Mint produced 6,403,287 of them in 1868-69. The JNDA designation is 09-28.
Obviously I'm no expert, but it does look genuine to me.
