Australian rainbow KG half pennies proofs.

Wanted to get some idea on what these two coins would each be worth.  They both are in great condition with super nice rainbow toning.  I purchased these two because their toning is extremely beautiful.  I expected that they were polished by someone prior to the toning.  Once I received them I discovered that the usual offset around the letters and around the rest of the items on each side of each coin had none.  There is no difference in any surfaces.  The finish of the smooth shiney letters blends right in the fields even under a good microscope.  Does anyone have an idea of what they would possibly be worth?  One is a 1949 proof ½ penny with “penny.” and the other is a 1933 proof ½ penny.  Is it possible to polish a coin to proof state and have all the items on the coins surface be uniform with no gunk inside the A's, R's ect…?  Oh yeah, before anyone says something, I know the photos suck but my description should tell you all you need to know.  I also realized that Australian coins of this condition can be valuable.   So what do you think.  Thanks in advance.

You'll need to take them out of the flip and take images were they are in focus otherwise nobody can say anything for sure.

The 1949 half penny seeing that it is a ‘proof coin’ and ‘minted at the Perth mint’ then it could be one of the highly sought after very very rare half penny proof coins as only 16 of these were ever made and they were favorably given out to either well known numismatic enthusiasts, museums or other mints. We are lucky to see one or 2 surface at any major coin dealers or auction each decade. So depending on its certification and grading quality it could easily fetch anywhere from  $15,000- $19,000. I think the last one to appear at an auction sold for $19,000 in 2022. Ur best bet is to take it your nearest coin dealership or auction house and get it appraised. 🙂 Good luck
