I remember on slack a user name the same as you said I painted the gold on the silver coins. Obvioulsy that was just a user name I can not say it was you 100%
Have I questioned the quality of the gilting on the 0.05? Yes, and if I remember correctly, when questioned about this you admitted that it had been done using a gold pen. Gold pens with real gold in are available I know as an artist myself, however, I believe that due to the poor application of the pen onto the coin, it made the process very obvious and affected the overall quality. This then brought forward the question of how they were gilted in the first place and with your answer it was clear it was not done in the traditional method therefore not what I or other were expecting.
As a reseller of high quality goods from a variety of sources, I always seek out the very best for my customers, it's why many come back time and again. SO, I believe it is incumbent upon me to do the due diligence on ALL coins I supply, especially when you consider the growing amount of fakes that are appearing on ebay. Titan springs to mind as a brand that has been copied relentlessly.
Along with this I (now) also check all coins when I receive them as, through time, I have learned that not all coins are as described or marked. This can be from materials used to codes not present under holos. It's been an interesting sometimes painful and also disappointing learning curve as trusted makers have either failed to produce a quality product or have outright stolen funds.
If you feel that me questioning the "build quality" of a coin you have made has cast an aspersion on you then I am sorry, that was not the intent but I would hope that with the above explanation, you understand why I would ask you. Does this highlight malice on your part? I don't think so, but I think that the processes by which you have historically created coins was the issue rather than anything else.
Again, your call
