I assume this exclamation is because of a stamp's price. Then again to the collector with this gap in his collection may think differently. Hope is the salvation or demise of the human race. I think all collectors are confronted in their lifetime with items that are too expensive and at some point later may have the funds to fill the gap. In my young collecting year (as most mortal collectors) I was confronted many times with items to steep for my pocket. Now I could afford some I wished for 50 years ago. But then today some other item may be beyond my price range adding the acquired temperance to abstain. c
Bravo! This little gem as we go back on its own time value we could say $5 bucks Austria dollars worth then after a couple decades it has worth 50 times for the original value. If we all know this thing to keep those stamps for a collection's hobby we might be a millionaire right now. Antique stamps can be a good treasures and it will be sold higher than expensive clothes.
The bigger unknown is how to keep such gems in pristine condition, poorer quality would be sold for much less.
In 1953 when the stamp (Michel 986/Scott C57) was issued 5 Schilling(s) were equivalent to about 25 Cents US. It is not surprising,that it did not sell in the auction: the starter price was very high indeed ! NZ$ 160.- are roughly Euro 115.-. Checking dealers lists,I found prices ranging from Euro 45.- to Euro 80.-. The quality is not exceptional as far as the picture can tell.Just the normal standard for german countries.A perfect gum side is also a normality.
