I went to casinos in Frankfurt, Wiesbaden and Mainz last week. I have loaded a page about those casinos, with pictures of tokens and low-denom chips. Club cards are also shown. http://www.jnmcnally.com/germany.htm

Thanks to Fran and Bjoern in particular for the advance info they provided.

The airport casino is not closing - it is relocating to another terminal in April and adding a second location in June.

I have some items for sale:
2 euro chips from Mainz and Wiesbaden for $5 each
towelettes from Mainz, Wiesbaden Frankfurt for $1 each
Slot tokens from Wiesbaden & Frankfurt for $3 each.
Postage $1 per order for USA/Canada
Checks, money orders, cash, PayPal (no added fee) are all accepted
