Hi Puzzler,
I think you're getting a little carried away with pricing!

My catalogue is a bit out of date (2009 SG Part 1) so I'm sure the catalogue prices have gone up a bit...
1. The 2½d blue Victoria stamp is SG 388 from 1901 (not a postage due) price 35p used, but no value with the corner torn off.
2. The 2d Foreign Bill revenue stamp is Barefoot Foreign Bill #74 from 1871 with minimum price.
3. The 1d green Victoria revenue stamp is Barefoot #55 with minimal value (10p in my old 1996 catalogue) but it has a damaged corner and is creased.
If this had been postally used it would have been SG 312 yellow-green price £1.50 but is worth much less used as a revenue.
4. The 2d violet Victoria stamp is SG 314 or SG 335 price 10p to 20p.
5. The 1d brown-orange Victoria revenue stamp is Barefoot #68 with minimal value (again 10p in my old 1996 catalogue).
If this had been postally used it would have been SG 313 or SG 332 price 10p to 30p but worth less used as a revenue.
6. The ½d New South Wales stamp could be one of many starting with SG 271 (which is grey but most are blue-green) onwards with prices from 20p upwards depending on shade, perforation, type and watermark.
