Australia Stamp Collection (early 1900's to 1970s) from estate sale; 104 stamps

Description

these are from a stamp album I got at an estate sale a while ago, these are the pages with stamps from Australia, they appear to date from early 1900's through early 1970's ... I do not know much else about them but it appears as if someone put prices or values on the pages above or below the stamps themselves with a pencil (done long ago I imagine?)
there are about 104 stamps attached to the multiple pages, I think I got them all in my photos
