Sorry if this is a dumb question, was this a coin/private key created by the creator of the coin or is it a DIY?
Based on the way the firstbits look in the hologram's window, I'd say it was legit from CI.
Yes, the first bits appear to be genuine.
The coin had a late load date though in 2016:

I had a few CI coins and I realized that often the laser-marked serial is either very hard to read, or had degraded beyond recognition - Not to say this had one, I have no idea, but I did have a coin where I brought it up in the sales thread, just can't find where/when at the moment as there were so many.
I know there has been some talk of certain CI coins showing first-bits degradation over the years. Seemingly, may be just dependent on said coin/paper....
And have not heard of the lasered numbering showing signs of degradation, but anything is possible
As long as the first-bits are readable, CI has released all addresses for their coins except the Rocket silvers, which most addresses are in the Master Maker Thread here:
