Coin Week" started in Russia to exchange small spare parts. From October 26 to November 7, you can exchange the accumulated change for paper money in stores and bank branches or credit your account (the latter is only available in banks). Bank of Russia coins issued since 1997 are accepted. To save time, the organizers recommend sorting them in advance by face value. You should also take into account that some sites do not accept coins smaller than 1 ruble.
