India Scott 156 is 3a Yellow-green Dak Tonga - SG 253
Scott 104 I'm not 100% - I think it's SG 192, the Nine Pie surcharge on 1a rose-carmine KEVII. Someone else will need to confirm this.
India confuses me, and by the look of auction sites, it confuses a lot of people!

Imagine being able to buy stamps with pies!
