Funny you should ask about 'ante', Pat. Just a day or two ago I was looking up this very word after listening to a hip-hop track 'Ante up'. I wondered whether this was common usage or one used only in that tune as a metaphor from the reference of raising the basic stake, e.g. in a game of cards. Turns out one might say 'ante up' in a few cases (e.g. when tallying), so I guess 'ante up' is pretty well known, just not to me.
I can't really help with your query though. [strolling off]
