    Are CGS still accepting coins for grading?

    Crypto

    In Australia and assuming you cash in your crypto at a profit you will be subject to capital gains tax at your marginal tax rate. If the asset is held for more than a year the capital gains tax is 50% of your marginal tax rate. If you make a capital loss on crypto then you can offset that against other income. This is true for most investments, shares, real estate, etc. I don't know what the tax implications are in the UK or US but there are probably some.

    Crypto

    Sorry we will have to agree to disagree Crypto is nothing but a giant Ponzi scheme. At least with tulip bulbs you can plant them in the garden. I think I will stick with physical gold.

    Crypto

    IMO crypto is a scam and a vehicle for money laundering. National currencies are not perfect by any means but as mentioned earlier do relate back to the real economy, Whereas crypto has no intrinsic value whatsoever. Where the money goes to after the purchase of crypto is anyone's guess but one thing you can be sure of is it is not held in reserve in case of a run on the particular crypto. Crypto has all the hallmarks of a Ponzi scheme and would collapse tomorrow is there were a serious run on it.

    One That Got Away?

    And the price is on the heavy side. Here's my example CGS 85.

    One That Got Away?

    Ebay's Worst Offerings

    1902 Proof Silver Half Crown Coin Edward VII | eBay One of the worst fakes I have seen
  8. Probably correct for the time, but times change. The Chinese are now the quick witted and the Brits and the West in general are backward and slow in thought. Time to wake up to our selves. The truth always hurts.

    Florin diameters

    If you look up a word using Webster's Dictionary it gives US and UK spelling, and usage also the use of the word in a sentence. In addition Webster's Dictionary explores the origin of the word and when it entered the English language,. Also free online. IMO a superior online dictionary to the OED. Perhaps a discussion for the Nothing to Do About Coins strand.

    Florin diameters

    I should have weighed them as well.

    Florin diameters

    Made the following measurements with my trusty vernier caliper gage: 1888 29,24 mm. 1887 29,24 mm. 1912 29.25 mm. 1945 28.30 mm. 1927 RAM 28.56 mm. 1924 28.55 mm. 1895 28.35 mm. Just a small sample. * gage or gauge I like US spelling it makes more sense like mold for mould. In any case much US English is older English.

    Before and After

    delete" the silver oxide" just before the last sentence.

    Before and After

    Clipboard a is a coin I have had for a while that I brought in Melbourne for about $90. As you can see the toning is uneven and detracts from the coin. Clipboard b is the same coin after sodium bicarbonate and Al foil treatment. The only treatment I know that does not damage the coin as it restores the silver oxides and sulfides back into silver metal. I know many collectors like an even tone to enhance the coin but in truth the toning on silver coins is corrosion that damages the surface of the coin. The colors in the toning are the result of optical interference between light reflected from the metal surface of the coin and that reflected from the oxide layer on the coin in a similar fashion to oil on a wet road. the silver oxide. I think a definite improvement.
  14. Hi Jelida, I noticed you were interested in vacumm tube HiFi. Many years ago I worked for the MO valve company at Brook Green where they manufactured KT88 and KT 66 beam tetrode tubes. The section I worked in was concerned with UHF low noise triodes and microwave tubes also a CV4085 that was a special version of the more common EF86. When I finished there I had an HNC in electrical engineering and went on the gain an honors degree in electrical engineering in Australia Ozjohn

    Using acetone to clean coins

    I've found metho and a wood tooth pick useful for removing verdigris from the lettering around a .500 Ag coin also a cotton bud for removing any remaining debris. I've heard there was some criticism about the dye residue from mauve metho. I don't know about the UK but in Australia you can get metho with out any dye. Also useful as stated above for degreasing a coin.
