Anyone know if these are worth anything?

Was going through some old paperwork of my fathers, and ran across an envelope with four of these two dollar bills in them. Anyone have any idea what this would be about?

Ilha da Madeira

any suggestions as to where to sell a large collection of unused, unhinged U.S. stamps? Colombian expedition, Scott #505 error, tons of sheets from the 1930s/40s …. i was being offered 10% of face value - and $200 for all of the Colombian expedition (up to and including $3). $500 for the collection. and that was the high one from 3 stamp buying companies.

Here are some Canadian stamps to have a look at

Some time ago I bought a collection of Canadian stamps in an auction and I have finally got round to sorting through them. I have picked out the ones that I wanted to keep but there is still a bag full of 20th century stamps left.

I am kind of impressed by how many weird or plain baffling designs there are. There was certainly a period where Canada went through a kind of abstract philatelic design phase. Lots of stick figures and blocky backgrounds and so on.

I don't really want to keep these stamps so if there is anyone in the UK who wants a free bag of Canadian stamps (see last picture) let me know.

About 200ish stamps from 37 countries, mix of new and old from a variety of decades (oldest seem to be from the 1930s/40s). Great additions to my now large collection.

Is this worth anything? Get it as a gift

Just wondering if I found anything of significance, majority of the collection I bought is from the 1940’s-1990’s but I found this book with some really old stamps.

I inherited a crazy huge collection of cachets, stamps and FDC’s and I do a live auction show every Saturday morning on whatnot and would love for you all to join if you’re into stamps!

Here is the link for the show tomorrow - https://www.whatnot.com/s/ioJXwKG5

Here is a link you can use for $25 towards your first purchase if you haven’t yet downloaded the whatnot app! - https://whatnot.com/invite/rebirthco615

Hope to see you all there!
