How much is alts in dollars?

Excuse me, as a seasoned practitioner in the realm of cryptocurrency and finance, I'm curious to inquire about the current market value of alternative cryptocurrencies, commonly referred to as 'alts'. Could you please elaborate on the current dollar amount these altcoins are trading at? I'm particularly interested in understanding the general range or average value as it fluctuates daily. Additionally, is there a specific altcoin that you believe is worth mentioning due to its recent performance or potential? Thank you for your time and insight into this matter.
