A yellow One Shilling and Threepence stamp could have originated in almost any of the 50 plus British Empire/Commonwealth countries. British stamps do not have the country name on them, all others do. You need to specify the country of origin, the design on the stamp, its condition, and the date if possible. An rough indication of the date might got from the post mark if it is legible. If the post mark is illegible or makes the detail of the stamp difficult to see, the stamp is probably worth nothing.
More information is needed. Please post a new, separate question with the bill's date and a description of the misprint.
