Hello,
In the pas 5 years, the highest price for a .com domain with the word Ticket as the first keyword was 4,734$ for TicketTrade.com, others like Ticket Bro & Tickets 247 were on the low 4 figure range.
If it was Tickets Mint or Mint Tickets, it would be a better name. 14,999 $ is over priced in my opinion especially that ir's not registered on any other extension. I see it as a 3 figure name at most.
Wish you all the best!
