The last three scans show postage issues. The "Jubilee" issue is Scott #114, the "2 Atts" surcharge looks like #46. The "9 Atts" will be #112.

Those aren't scarce stamps, but all three are in nice multiples and there are very likely minor overprint varieties among them. (There appears to be pencil notation on the 2 Atts block showing such a variety -- differing spacing between the Latin and Thai surcharges.)

The rest are fiscals, and I'm not sure about those.

And just to let you know, the catalog value in the 2018 Scott Specialized Classic catalog for (hinged unused VF, never hinged of course worth more) examples: #46 is $6 but the spacing variety is not mentioned, #112 $16, #114 $7.50.

Thank you so much I am going to check it out and post the update

The oveprints on Revenue agriculture the bottom line is number but can someone translate the top two lines ? Any Idea what does those numbers mean ?
