The 1825 Extension Kit: G1 is an expansion for 1825, an 18xx game. It includes extra money for use with any of the 1825 Units (useful for those desiring a long game) and is required when paying with 1825 Extension Kit K3: Phase Four. The expansion contains £10,000 in the following denominations:
£25 x 8
£200 x 14
£500 x 14
It is not advisable to add the extra £500 notes to an 1825 Unit unless an additional extension kit is in play.
