Coins Mint Proof Sets

I can understand a commemorative coin that celebrates the 100th anniversary of an event, but why do we need coins for the 150th, 175th, and 200th anniversaries? Have they run out of ideas and just decided to start repeating coins every 25 years? And how many commemoratives are out there now for Lincoln, and the Lewis and Clark Expedition?! Out of all the events that have happened in this country’s rich history, why do they keep commemorating the same things over and over? I understand the US mint is a business and is trying to make profit, but does this seem a little ridiculous to any other collectors or is it just me?
Sorry I need to clarify: By the Lincoln and Lewis and Clark commemoratives, I was also including the regular coinage that get’s "commemorated" like the Westward Journey series of Jefferson nickels a few years back, in addition to the US Commemorative Coin program coins. The Sacajawea dollar (Sacajawea was part of the Lewis and Clark Expedition), and the Lincoln cent which in itself in 1909 was a 100th anniversary commemorative. And they are now releasing 4 more "commemorative" versions of the cent for his bicentennial.

I’m not sure what it’s made of, it looks like it could be gold plated but I’m not sure, it’s kind of dull. On the front there is a picture of Millard Fillmore and it says at the top "Millard Fillmore", and at the bottom it says "1850 13th president of the united states 1853". On the back there is no picture, but it says "Millard Fillmore Born Jan. 7, 1800. Grew up in a log cabin; Last pres. of Whig party; opened trade with Japan, Installed first library in the white house. Died Mar. 8, 1874." Does anyone know where this coin came from? I looked through all the commemorative coins in the US mint and it doesn’t say that there has ever been a Millard Filmore coin that was produced (or if it did I just didn’t find it). I know they are supposed to release a similar version in 2010, but I’ve had this coin for a long time and don’t know how I got it, it might have come from a relative.

My wife asked me a question, and I couldn’t give her an answer, which always bothers me. So I thought maybe I could get an expert opinion on here.
I have a .999 Fine silver Commemorative Liberty Coin. The coin is dated 1991. The coin weighs 1 lb.

So basically the question is what does a 1 lb .999 fine silver commemorative coin sell for these days? Has a picture of lady Liberty on front, with the year 1991, and Eagle on back.

It is basically this coin

But instead of "One troy pound" on the back, it says "1 LB. .999 Fine Silver" The date on front is 1991. Other than that, same coin.

I have a bronze commemorative coin from when Prince Charles and Princess Diana visited my school in Australia. There are maybe 100 in existance and I would like info on it’s value.

Front side reads: "Portland Proclaimed a City On Monday 28 October 1985" (with a seal of the city).

Back side reads: "Commemorating A Visit to The City of Portland By Their Royal Highnesses The Prince and Princess of Wales On Monday 28 October 1985"

Any information is welcome.
