The cash ban at the Roman Baths aimed to reduce damage to the 2,000-year-old structure caused by coins being thrown into the water. The practice had led to water damage and the decline in cash usage post-pandemic further supported the decision to switch to contactless donations.

The Roman Baths banned cash donations due to a "notable decline in the use of cash" since the pandemic and concerns that coin-throwing had "begun to damage the 2000-year-old structure." The process to collect coins was also time-consuming and wasted water, with some coins being "garbled" and unable to be banked.

The Roman Baths lost £90,000 ($170,000) in donations after banning cash and implementing contactless payments at the wishing well2. The decision was made due to a decline in cash usage post-pandemic and concerns over structural damage caused by coin-throwing. However, this move resulted in a significant drop in donations, with only £10,812 and £9,490 collected in the following years.
