Slovenia - "Idrijan Lace" 1996:

Most of collectors know Slovenia by as new (in)dependent country that separated from Yugoslavia, in 1991.

From beginning, they issued, I can call it, "acceptable" design, but very questionable quantity of postage stamps, which made some "backfire" after AFINSA scandal (scheme). Quantity they print range from one or two million, per set, or 300 000 per single issue, when some topical issue come, it was printed in half million stamps.

For country, that have two million people in population, we understand, that it was clearly, driven by "making profit for any price", and less for market need of Postal System, or people that send mail in "old way".

I was able to have all issues first 10 years, probably little more, so when in 1996 year come issue under name "Idrijan Lace", I was not, well, focused on design, as it was one color design, and in some strange form of printing sheet, that I didn't like.

Over time, it come information that this issue have, some kind of security print, background print in FC, which is visible under UV light, with post horn image and "1996". So, again, I check in catalog/s, see it have no "special" impact on price, and I just close my stock album.

To people that use Michel catalog, they will find it under number (basic set of 12 values) 153-164, and in Scott catalog under number 261-272. Need to mention, that set is issued in six pairs, and catalog value are for set of pairs, where separated stamp will affect market value.

Than, friend of mine, informed me to take care about this back ground overprint, or as they call it, security printing in fluorescent color. Normally, I check the Michel catalog and yeah, it is here!

Three type of it, indeed! Michel made change in listing, to:

153-164 x, 153-164 y I+II and 153-162 y III+IV

First and second option have it stable 6.00 euro per full set in pairs, but this third option made it hard for Philatelist!

Scott catalog have it mentioned in description under listing, where they inform, that "1997" year back print have catalog value of 150.00 US$. 

It is set of just 10 stamps (5 pairs), with "1997" background print, and catalog price are for it great 130.00 euro.

Problem come when You try to purchase it, because it have low quantity made, and not everyone have it in stock, recently, I wanted some samples to buy from Slovenia, but most of dealers there have no one to spare, and that what was available, come to asking price of more than full catalog value.

That was reason, why I put this issue under title "Stamp must Have", where I will suggest to all - check Your album for what You have there!

Yugoslavia (classic period)

YUGOSLAVIA:

...not just classic, but specialized classic material, which is very hard to find on open market. Than come next one point, it is in mint, never hinged condition, that is valued in catalog almost twice the catalog price.

Here are Michel numbers, which, if You will check in Your collection, is probably missing:
A 19/20 I, 30/32, 139/44, 164 A+B, 320 C, 348/49 F, 348 E, 356 B, 430 A, 439/40 A and great 439 I (with engraver "S" mark).

Go after it, as catalog prices are constantly going up for this kind of material, and scarcity on open market are very visible, even on eBay You will not find it!

Yugoslavia - CETINJE issue 1945

...this come on end of WWII (1945), as fresh made Yugoslavia, overprint on Montenegro issue (under Italy occupation), set of 11 values, 

and additional PORTO issue of two values.

As technology at the time was not so advanced (according today's standard), there are some errors in typing, probably in printing plant, there are some missing latter so worker use "similar" letter in composing this overprint.

Here You can see one error on "A" letter (instead, used "D").

Michel catalog value it well, two sets and one value with error, can reach on market more than 700.00 euros, as this issue are very hard to find on market, reason are 7000/10 000 sets printed.

So keep an eye on this issue, and if You can afford, buy it!

Czechoslovakia 1919

Here we come to one "Diamond" in every collection.

Nice or not nice, it is one classic issue from 1919 year, overprint on Austro-Hungarian stamp (Michel number 205 II), catalog Michel have it by number 56 IIb, 3 Kr lilarot (lilac red), 

overprint "Posta Ceskoslovenska 1919" in black color, and Scott have it under number B19a.

Examining Scott and Michel catalog, also Specialized Czechoslovakia catalog, I see that this issue is not summarized in "set" like we know to name some issue of x, y stamp in issue - that mean, this overprinted stamp come to the use "as situation required" but here we have too much to study, which is not my intention at present - I'm not so big specialist in this field.

Now, why I think that it is worth to have?

First, it is early period of country, after that one more reason is overprint alone, next come that this specific stamp is not in "basic" set - mean, that "basic set" value of 3 Kr come in brown-carmine color, and here shown come in claret. Scott mention this "variety" (number B19a), which is actually not variety, but regular color of original Austro-Hungarian set. 

I just purchased this one lot of 4 stamp, where between four, one is exactly mentioned number, in VF, LH condition, og.

What decided that I go after it was, rarity of this issue, and because it (specific stamp) is signed on back, which actually is some kind of certificate about same. I don't have wish to track and buy one sample with certificate, also because it will be so costly and also because not many of this stamp are know. Signature on back actually give me some kind of secure sleep, when is talking about forgery - but, without certificate it still have one level of chance that it can be "bad".

I also read little about this stamp in "Specialized Guide for Czechoslovakian Stamp" which say that color is correct and also dimension is correct, actually existed "small" (25x30 mm) and "big" (25.7x29 mm) dimension, which just confirmed that I have right stamp.

What say catalog value?

Michel 2000.00 euro, Scott 2750.00 $ and "Guide" (don't have prices - but "points") marked it 2R (mean: 201 to 400 know discovered). If I know that my sample is in VF, LH condition, that will reduce level to one fair market price of around 60-70% of Michel catalog.

Want it, have it? Keep for it, and if it is in Your collection - put it on the bottom of box, as dark side as can be - it is really one valued stamp!
