Huge Favor Can Someone Please Take The Time To Verify My Recent Discovery Of Significance Accurate

Hello,

I'm hoping someone can verify the accuracy of my observations regarding a potentially rare and historically significant stamp. Based on my research, it possesses several unique features that suggest it could be of considerable value.

1. Early Date and Significance: The stamp is postmarked from Co. Dublin on August 3, 1921, at 5PM. This date coincides with the very early days of Irish independence following the signing of the Anglo-Irish Treaty in July 1921.

2. Unique Characteristics:

Rare Color: The stamp has a deep orange color that appears to be a [specific shade description], which is different from the typical shade used for this issue.
No Overprint: Unlike most stamps from this period, this one lacks the "Rialtas Sealadach na hÉireann 1922" (Provisional Government of Ireland 1922) overprint. This could be due to its exceptionally early date.
3. Inverted Watermark: An image of the stamp (Images are below) clearly shows an inverted GVR and crown watermark, adding to its rarity and potential value.

I would be immensely grateful if someone could verify my observations and provide further insight.

The overprinted stamps weren't introduced until February 1922. There are around nine shades of the 2d orange.

Gibbons has a note at the beginning of the KGV section pointing out that stamps of this era will be found with watermarks reversed, inverted, or reversed and inverted; they don't list them. (I didn't dig out Vol. 2 of the Specialised, but Commonwealth doesn't list them.)

They note, and list, a few "missing watermark" varieties, as well as a few "watermark sideways" varieties which are normally coming from rolls.

My 2015 Stoneham Catalog lists the inverted watermark variety. In their listing of values, a used normal watermark is 0.25 whereas the used inverted watermark variety is 5.00. Of course, condition is everything. They also list a watermark inverted and reversed, watermark reversed, and watermark missing. As stated earlier, there are several colors listed. So, you have an interesting item that may be valued a little higher by some collectors.

It is a common stamp from a stamp book valid in the United Kingdom of Great Britain and Ireland. You can see this from the cut perforations at the bottom. As GeoffHa points out, the provisional government overprint was not released until 17 February 1922, and never in a booklet. the clue is in the overprint 'Rialtas Sealadach na hÉireann 1922'. About half the booklet stamps had an inverted watermark.

Your stamp is a type 1 stamp. Type 2 did not appear until September 1921.

Although it is tricky to tell the colour from a scan on the web, it looks like either the yellow-orange or the pale orange one. These are amoung the commonest colours.

The 2005 SG Specialised assigns it a used value of £ 10 as inverted watermark stamp.

The stamp itself appears very fine, at least. Its is a nice addition to a collection of these stamps but nowhere near rare: quite common.

Unfortunately, the true colours are very different from that in the scan. But it shows the wide range of colours for this issue.
