hose stamps are what collectors call "semi-postals". They pay for postage and an additional amount that goes to some worthy cause. They were issued in 1922 and have a 2019 "catalog value" of $109.00. If they were used, the "catalogue value" would be $625.00. They were issued without gum. Yes, stamp collectors would want them. So handle them carefully. Google this "I Inherited a Stamp Collection, Now What?"
Since stamps were first issued in 1840 stamps of 1922 are not particularly "old". Remember this too, a stamp catalogue value is not like a Sears catalog, where the price you see is what you would expect to pay. STamp catalogues only give you "relative values". Dealers will pay a discount of catalogue because he has to resell them and he know we stamp collectors are very tight with our $$
Those are nice stamps. If they are any indication of the others in the collection, well I am sure we would all like to see more!
Your stamps are Scott B30 B31 B32 B33. Your city library may have set of Scott catalogues. But, be sure to educate yourself with that google suggestion I gave you before you get carried away.
