Are mule coins worth money?

Are mule coins truly valuable investments, or are they merely a novelty item with little to no monetary worth? As someone interested in cryptocurrency and finance, I'm curious to know if these coins hold any significant financial potential. Do they have a track record of appreciating in value over time, or are they more akin to collectibles with limited market appeal? Additionally, what factors should one consider when evaluating the potential worth of mule coins, and are there any red flags to be aware of that could indicate they're not a wise investment choice?
