The fact is that the Telegram team in October 2019, preparing for the launch of TON network, released a limited number of GRAM test tokens. Then on November 16, the Ton test network was restarted. Old tokens burned down and were reset. The distributions of new tokens began, which did not intersect with the old.

Test tokens of the second emission existed in the test network Testnet2. After making Pavel Durov, the decision on the closure of the TON project, interest in the test gram fell, but then everything changed. Team Telegram handed over to the Ton.org domain and the repository to the Ton Foundation developer community, and all GRAM test tokens from the TON Testnet2 test network became "real" because for a year and a half there was a more or less normal distribution of coins between more than 70,000 addresses. Therefore, we decided to leave this particular network, and not to deploy a new one from scratch. Thus, Testnet2 and became MainNet.
