Greek Stamps - Are They Real?

Given what I paid for this collection and my unfamiliarity with Greek stamps I would like some input as to the authenticity of the attached stamps. Any input greatly appreciated.
Perf12 these are some of the items from our previous discussion.

Wheelman, why did you not post these ith your previous discussion, or at least give us a link to it? It ould certainly help a lot.

Peter,
A completely different question. Perf12 asked if I would post some pictures from an ebay acquisition so I was advising if he saw this that these are from the same purchase. The previous post was regarding a cover and therefore I did not think it appropriate to post individual stamps in a cover related post. Sorry if I screwed up.

Hi; They all look authentic to me.The first row looks like the consecutive athens printings.The bottom right & the 1st stamp looks like the cream colored paper printings without control figures..The bottom green maybe a meshed paper printing?(Need a close up pic of the back & front..
if you could post a pic of the 2 stamps individualy(in the bottom 10 lep orange & 20 lep blue)second & third from the left? Need a close up clear pic too check out these stamps.
The Hermes head stamps spanned over 20 years.The same plates were used in different conditions and places.(Paris ,Athens) Paper & color differences are very frequent.
Short margins cutting into the frame on these stamps means the prices go way down. -70%

I would think it must be extremely difficult to tell early Greek forgeries from real stamps given only a scan. I have difficulty identifying these stamps in terms of Scott numbers!

Thanks for all the replies on this.
Perf12. Scans follow. I noticed a couple things on the 10 lep - It appears to have a hinge remnant on the front and the 10 is reversed on the back. Thanks again for your feedback on this.

hi; Could you take a good clear pic of the 10 lepta orange?..It is very interesting.The maximum in pixels you can post.
For the 5 lepta green ;seems to be the 1871/2 printing.The photo of the back is not good enough to see if it's a meshed paper printing.The color
of coarse counts a lot,and fit's in to the 1871 green colors.But the meshed paper printing also had this green shade(sage green).
The orange stamp needs a clear big photo.
The 20 lepta looks like a meshed paper printing(1871-76),again you must confirm.

Perf12 - First thank you for all your assistance on this. This picture is taken in 22MPX macro RAW mode. The field of focus was very narrow so the right side is a little out of focus. It was also taken using a incandescent light so it has a yellow cast. Will need to use previous pics for color. I have not yet soaked the hinge remnant off the front thus the shiny part top center.Hopefully this provides the detail you are requesting.
Thanks again - Paul

Forgot to re-post the back.

Judging from the printing of the control numbers I would put this stamp
in the 1867/69 cleaned plates issue.Now the color difference between your 2 pics (orange-red in the small pic ,orange in the close up makes things hard for me).If it's more redish that makes it more interesting.I don't know the plate number of the inverted 10 in the Cleaned plates printing.I don't have the specialized iliterature on control number plating.Maybe someone in the forum has this.
If on the other hand the stamp has releif on the white parts of the face and neck we can easily place it in the 1862/67 Consecutive Athens printing.Even in the close up can't tell if there is relief.You will have to check this out .It is quiet apparent if you look at it from an angle.
