Good to know, I fund all my coins. This rationale shouldn't affect the premium however, just the demand for the coin.
It affects the premium for me and creates a much higher barrier to entry for the coin. It's fine to fund your own coins but when you fund (initially unfunded) and then try to sell them online it's a lot trickier especially when you expect the price to be increased by minimum X amount where X is the value of the funding.
Unfortunately I can't find the certificate that came with the coin. I'm not really looking to sell right now, just curious of the possible value. If I were to sell, I could contact the maker and ask him if he possibly has a copy of the full address to prove that it's not a vanity address.
That's a bummer, I know some people are comfortable gambling on that amount but without 100% certainty that coin is funded with the stated value I will not be bidding.
A good question at this point in time would be:
How did you fund it without having the certificate? I'm guessing the funding took place when you initially got it before misplacing the COA?
I'm the original purchaser of the coin, I funded it shortly after receiving it with mined Bitcoin (why I said they are virgin coin). The first 5 coins were graded by the creator before being sold. I must've had the certificate, but if not I would have funded using the first bits. I recently moved across the country so it's possible the certificate is still packed away somewhere. Seems strange that I wouldn't have kept it with the coin if I had it, but anything's possible.
