These data are used for training, testing, and evaluating the CycleGAN project related to coin reconstructions. Data are used to train the given CycleGAN model and coins are used to evaluate the model both internally, computationally, and by other users. This file provides training data obtained used to train the CycleGAN. There is a training folder which contains two folders (mixedBadCoins and mixedGoodCoins). The mixedGoodCoins folder contains coins that are better preserved and used to train what a coin should look like. The mixedBadCoins folder contains damaged coins and attempts to train to reconstruct from these coins. The name of each file corresponds to coins that can be found using the identifier for coins referenced on These are image data used to test the developed CycleGAN model. The images folder contains the testing data used to generate model test data. The names of the coins correspond to the identifier on

CoinsEvaluation.pdf: This file is used by testers to evaluate if they think given reconstructed coins shows improved quality or not from the real coin. The users are asked to evaluate coins on a 1-5 scale, with 1 indicating no difference and 5 indicating much improved reconstructions. This was used for evaluators and the folder contains real and fake (i.e., reconstructed coins) coins used to ask judges or users to determine if they can tell if a given coin is real or reconstructed (i.e., fake). In addition to the real and reconstructed coins, a pdf (Real_or_Fake.pdf) is used to ask judges to determine which given coins are real and which are generated reconstructions. This is the final CycleGAN model used for reconstructions applied in the paper. This contains relevant parameters and an example of how training is conducted. This is a zip file containing real and fake (generated) coins from the model output. This contains all coins evaluated for the paper's results. The index in the folder provides visual representation of the real and generated coins.

Coins_for_Figures 2_and_3.csv: This list helps to correspond the number (in the paper's figures) and identifier used in Figure 2 and 3 are used to show these example in the paper.
