How do I make coins ?

Hi, I've made a game that is endlessly scrolling and is made of pre made maze scenes that are loaded in from another layer. However I want to add coins in the maze that are are equally separated. How would I add this without having to add each coin individually?

I used tiled for making the mazes using the auto tiler feature, would I be able to do this using tiled if I can't do it on construct?

thanks (sorry for lack of knowlage, being noob, grammar etc)

P.S I tried uploading a gifs to help show what i'm actually making however school network doesn't let me upload to githy

There are a few ways you could do this, but they can be a bit convoluted if you're new to this stuff, still totally doable, just non-trivial. My first question would be, how are you using these maze sections within C3, are they sprites? Do you have collision information for these sections? Or tile data for them? Or are they just flat images you've imported?
