That sounds really cool! If you do release it be sure to price it to where 12 year olds won't reveal it on YouTube.
I like Lipsmacker by Paul Harris for anything mint related. For coin magic, there is a plethora of variations on coin magic so it's hard to give a recommendation without specifics, and my favorite ring flight is Ring Flight Revolution by David Bonsall. I have reviews of both Lipsmacker and Ring Flight Revolution on my YouTube channel along with live performances if you want more info on those effects.
As far as my personal favorite to perform that doesn't include cards, it's a routine I use for stage illusions where I'm stripped down to swim trunks, locked from neck to my ankles in industrial chain, and then put into a standard issue mail bag that is locked at the top and none of the locks are gimmicked. Before I introduce the audience to the three parts of the magic trick in The Prestige (Pledge, Turn, Prestige). The being locked up and put into the bag is The Pledge. A screen is briefly put over me to reveal that I failed in my escape which is The Turn phase. But then the music changes to a completely different style and a transport into a previously empty location in clothes again. That last part is The Prestige. I have my stage manager narrate the parts of The Prestige that I previously introduced the audience to the concepts with Double Cross.
