The Thunderbird Hotel was located at 1213 Las Vegas Blvd and had two different slot machine tokens. Both were dated. In August 1987 the token was made by the HH mint and had United Coin as the slot machine route operator. In September 1988 they dropped United and had to get new tokens. This time they got them from SSM mint. All of this information is in my Gaming Token Book. E-Mail me and I'll give you more information about the book.
