Even that I deal with stamp for more than 25 years around, rarely that I come across items like this issue, which recently, I sold to my client that I will be free to say, is collector "Who Know What Philately Is"!
About what is talking?! For sure, about stamp, that MUST be included in any serious collection, if - IF - we (collectors) want to leave collection worth, to our future generation!
Here it is one short description:
"First Coin" issue #1-9 (in all categories), that is issued by Israel on 1948 yr. Some stamp from this set come to my hand also before, but never in this perfect condition, even that 1-6 is really great condition, I didn't manage to find last three value in mint condition, but was happy to have 7-9 in perfectly used condition, that will fit well in my client hands! If it is worth this investment? I think - yes! Why? See, Scott for 2006 valued it at: 1-6 mint + tab = 210.00 $, and 7-9 mint + tab = 4750.00 $.
Searching around most know auction and dealers, I didn't manage to find prices in this range and 1-6 is worth around 550.00 $, 7-9 used only I managed to find, and this go for 1900.00 $.
What is more important, is that for this kind of investment, preferable is to have it examined and certified - because this money is worth it! Here in picture, You have it shown - and I think it is great! Yes, certification will cost You additional expenses, that can reach, for this set - more or less between 250-300.00 $.
Worth this money? 2006 year 210.00 $ - 2012 year it is 550.00 $ - just don't say to me that it is "worth how much collector is willing to pay", because You and I know that it is worth it, even that not every collector is willing to pay it!
