United States Mint Tokens?

I have been gifted a few mint tokens and am curious if any of you have seen these before or how to find them on Numista at all. I think these things are pretty cool!

#1. Unites States Proof Set - Department Of The Treasury 1789

N#329747

The above page shows correct, but the reverse is different, as it says United States Proof set. Is the page likely wrong and I should update, or should I request a new page?

#2 20 years of liberty 1975 “Penny” 
Obverse on this shows a regular penny, but it is bowled on this side like a plate,  the reverse shows an octagon. with 200 years of liberty. I couldn't find the page for this either. 

Hello 🤖

Without pictures, it will be very difficult for anyone to help you. Could you please post clear pictures of each side of your item?

Greetings, MaxTheSpy.  If you're looking for U.S. Mint Set tokens, try using this query since I have some too in my collection and have noticed that they that appear under "Medals" in the Numista catalog here:
https://en.numista.com/catalogue/index.php?e=united-states&r=&st=220&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=&a=&dg=&i=&b=&m=&f=&t=&t2=&w=&mt=&u=&g=&c=&wi=&sw=

Providing pictures of both sides of your Mint Set token is more helpful to the community so that we can make sure that we're steering you in the right direction.  You appear to have this one based on the single picture that you posted for #1:  N#76904

For #2, please post pictures of both sides.  In addition, providing measurements for weight and diameter would also be helpful.  If the other side of your token shows a regular Lincoln cent, then this is not an actual U.S. Mint token that you would find in a U.S. Mint Set.  Instead, it's something else.

3.124g 

21mm diameter

1.65mm thick with the reverse design protruding about 0.12mm while the onverse of Lincoln's head is basically smooth. 

I thought maybe it was a re strike with a different pattern. But I don't see any evidence of a normal reverse anywhere.

As for the other coin you were spot on!

Thanks for the added information.   It looks like someone took a regular copper penny and had some fun with it.  

Their press job was rather crude since there are extra borders showing up on the 12:00 and 3:00 positions near the rim.  I'm not sure what to call this except for someone's own personal creation.

For #1 here is your token N#76904 It was in the 1982 proof set https://en.numista.com/catalogue/set.php?id=161

I made that page and definitely have the token.  It similarly was a gift/added bonus when I purchased some coins a while back.  Not sure where it originated though.
