Hi Howard! I'm assuming by brand you mean the cancellation on the stamp? I saw a similar cancellation on a KGV stamp from Australia on Ebay. It likely means that what you have is a cancellation from the Melbourne area that used to be prevalent back in the day. https://www.ebay.com/itm/1922-4d-UL...874330?hash=item522740c49a:g:LZwAAOSwihldL5oO
Many thanks to Hochstrasse. Thanks to you, I was able to find exactly my version. I think their price is equal. I correctly understand have these stamp-inverted color of? Why is this happening - the type of re-circulation?
Hi Howard, If I'm correctly understanding your question you are asking why there are so many iterations of the same stamp? Australia like the United States had long periods of runs of the same stamp design with different shades on stamps of similar denomination, different watermarks or no watermark, small variances of design and perforations. The Washington/Franklin series in the United States has that in common with the KG5 series'. I'm not a Commonwealth collector and really can't give you an answer on that end. In the States the reasons for variances in the Washington/Franklin series has to do mainly with technology changes: different printing methods, improvements in dyes, perforation technology and elimination of watermarked paper.
I have found my stamp here: https://findyourstampsvalue.com/stamp/search?q=three halfpence king red&country_id=6 but how to understand which is mine?
Hi Howard, It's likely you may have to check the watermark on your stamp. There is a wide crown with narrow "A" variety and normal crown with multiple "A" variety. I don't know how you accomplish that with a stamp on piece. If I had to guess I'd choose the first stamp which most closely resembles the color of your stamp. Because of color changes on older stamps the scarlet, carmine and rose red are sometimes hard to differentiate. The only way to know for sure is check all the parameters: perforation, watermark and design with the aid of a catalog. Good luck!
