Incidentally I found back that old thread. Incidentally also my scanner is working again. I thought about showing my pride but then I realized that I`m proud of most of my coins and that would take ages to scan it all in so I found another idea 
As this thread was about coin-identification, I will give you a small quizzie: behold 20 various coins from my collection, from different countries and periods of time and try to identify as many as possible (country, year/period, denomination) using the images and additional hints that I provided. only one side showed for some challenge.
ANSWER-TEMPLATE AND HINTS
1. (country) (year) (denominaton)
HINT: Probably one of the hardest examples. The text on the coin is: SANCT.MARC.V. Century is enough.
2. (country) (..78) (2 maravedis)
HINT: what eu-flag do you see here? The thing in the middle should determine the century.
3. (country) (year) (50 ...)
HINT: read also the text and not only the image.
4. (country) (year) (1 ...)
HINT: too easy to give hints
5. (country) (year) (2 pence, common name is? ...)
HINT: is the image masculine or feminine? The first letters are E.D.G.R... should be enough.
6. (country) (1954) (50 pyas)
HINT: only the country needed, the alphabet is obviously not latin
7. (country) (year) (denomination)
HINT: the text is arabic and I have only a rough idea where that coin comes from so if someone knows more about it anyway, I will appreciate it
8. (country) (year) (denomination)
HINT: no text, further the same as 7
9. (country) (year) (denomination)
HINT: hint should not be needed here
10. (country) (1984) (denomination)
HINT: the hardest part is the identification of those animals
11. (country) (year) (denomination)
HINT: at least the nominal value is somewhere on the coin.
12. (country) (year) (denomination)
HINT: approximate century is enough although the date is in theory idetificable up to 3 years error.
13. (country) (year) (siglos)
HINT: century is enough. the image is that of a warrior
14. (country - the "real" one) (year) (1 duit)
HINT: the name on the coin is not the country
15. (country) (1652) (denomination)
HINT: the text is: SOLIDUS.CIVI.RIG.5.2
16. (country) (year) (50 ...)
HINT: where is that building located in the world? Notice the stars.
17. (country) (year) (denomination)
HINT: no special hints for some challenge, century is enough (think of the time that that country minted most of its coins)
18. (country) (year) (denomination)
HINT: Those coins were struck in peculiar way from wires of metal
19. (country) (year) (denomination)
HINT: denomination requires some research, but the value was equal to 12 grosz.
20. (country) (year) (denomination)
HINT: think of certain eu-flag. denomination requires some research so know that coin isn`t gold or silver.
Good Luck
