One series I totally slept on.
From the chinese mint this 8 part series come with a mintage of 5000.
From LPM
"For the first time ever, a Chinese mint will laser etch the year, weight and purity on the rim of the coin. Limited mintage of 5,000 coins of each design, the reborn classic will be a striking addition to any collection!"

The premium on those is rising pretty quickly and from what I can tell so far they are well received.
I try to get my hands on some with the intension of flip some to have the whole series for "free" at the end.
I ve read they got released in a 15 week interval so far
