Quote: Where and how would the best place to get a bag full of Machins cheap to start with.
If you have none to speak of yet, and are starting a collection, you could do worse than buying some unsorted Great Britain kiloware on
ebay. Obviously, you'd need to select well. Some sellers will have off-paper, which might be better if the shipping is UK to South Africa. Also, the more recent security Machins are much harder to find, and the bulk of most kiloware will be pre-security issues (as it happens, 90 percent of the issues anyway) - and try do deduce how many 1st and 2nds the lot is likely to include because these become very repetitive - useful for hunting down the various imperf edges though.
I've recently drawn up my own lists for collecting these, and re-organised my collection. I've never had any interest in phosphor bands, gum types, print methods, and so on, which to me are just practical features rather than design features. I have separated out into sections as follows, the great advantage of which is that nearly all sections are closed, and can be completed - only the current categories are ongoing (ie, sections 9, 11 and 15).
1. Pre-decimal
2. (Decimal) Wide Value Types (1971-83)
3. Re-Issues of (2) With Narrow Values
4. Narrow Values Series (1983-91)
5. Back Prints (stamps with symbols printed on backs - hard to find used!)
6. Imperforate Sides
7. Re-Issues of (4) With Elliptical Perforations
8. Elliptical Perforations Series (1993-2010)
9. Security Features (2009 Onwards)
10. Regionals: Isle Of Man / Northern Ireland / Scotland / Wales
11. NVI - 1st Class / 2nd Class / Service-Inscribed
12. NVI with Imperforate Sides
13. Penny Black Anniversary (1990, 2000)
14. Anniversary Stamps With Imperforate Sides
15. Large-Format Booklet Issues and Oddities
