I think you should be sure that what goes on the ChipGuide is accurate.

I just checked the Club Union page from Costa Rica in the ChipGuide:

I sent in several of the chips. I just noticed there are 4 additional chips shown that I didn't send in. Unfortunately the chips are modern fakes. The real crest and seals were made in 1924. The fakes are ceramics.

The fakes are the green 20 colones, blue 50 colones, pink 500 colones and black 1000 colones. These chips should be removed

Btw I have some more Union Club chip to be uploaded: n/d gold, 10 pink centimos, 25 light blue centimos, 5 lavender colones, 20 dark green colones and 50 blue colones

For comparison purposes, the first chip is the one currently shown in the ChipGuide. The second chip is from my website
