What is a newspaper from 1945 worth?

This category of collectibles has a very volatile market. The prices for collectibles are based on what a collector is willing to pay for your item. If I can find your item on just about any collectibles web site. I probably will not worry about buying that particular item from you.

Now, if you have an Authentic Artist Signed Art Deco Poster featuring Abisinthe, which has renewed interest these days, and it is mint condition..I will probably pay whatever price you have on the item.

Market, scarcity, and buyers set the prices. Emphemera has a hard way to go. There were a lot of newspapers printed. I am assuming by the year it has to do with the end of World War II. Many, many people knew how important that war was from any other war in history and meaning of the end of the war. Most papers today were saved in trucks and bundled in papers, etc. Most are in pristine condition. Scarcity is not a factor. There is a sellers market of these newspapers.

Do not just throw the paper away. You will find a buyer and it will probably sell around the 20.00 range.
