In Portugal we use different colours with the same value chip to distinguish the differentpersons that are playing at the same time( in Spain is different and i think is very difficilt to know who winns)
The chips you reproduce were used at Grande Casino Peninsular, at Figueira da Foz, a beach in the middle of portuguese coast.
The chips were used at french roulette, and french bank (a portuguese dice game).
In Portugal in the black jack tables we use american style chips, from Bud Jones, etc.
The american roulette is not very popular in portuguese casinos.In the american roulette tables, there are not house chips, the casinos use chips with symbols ( in Estoril triangles, etc from Bourgogne et Grasset,in Vilamoura, helm and letter K in different colours, from Bougogne et Grasset,in Espinho anchor and helm, from Borgogne et Grasset, etc)
The chips from Casino Peninsular that you reproduce, were used at least from 70´s years, to the end of 2001.
The values of that plastic chips were:
10 five different colours, 20 six, 50 five, 100 four, 200 five, 500 four, 1000 four, 2000 three, 5000 three, 10000 plaque yellow, 20000 plaque rose, 50000 plaque orange, 100000(plaque chocolate).
In the end of 2001 were in use only the values 200, 500 and 1000.
Do you have anny duplicates to trade?. Some colours of the low values (20 to 100) are missing to me. I have to trade some colours of 200, 500 and 1000, that I only trade for chips of Casino Peninsular that i have not.
