There is no standardised symbol of St Thomas Becket, nor for any other English archbishops.
Visitors to the medieval shrine of St Thomas might buy one of a variety of tokens to take away with them, including lead ampulae of Holy water or so-called "Blood of St Thomas". These were usually in the form of a small, flat vessel with suspension loops so it could be worn on a string around the neck. Such ampulae could be bought at very many Holy shrines across Europe.
Pilgrim badges were also available in Canterbury, again often made of lead or pewter. These showed a portrait of the saint wearing his archbishop's mitre, or a scene showing his murder, or one or both of his gloves, or a star with six wavy arms, or an image of the elaborate shrine, or various other designs. I have several of these in my own collection.
