I have here what has been identified to me as an Ippyo Daikoku Hori Esen. I have a few questions about it that someone may be able to answer. Would anyone more knowledgeable in Esen or Japanese coinage happen to know more about its purpose, date (era?), or possible catalog reference? Hartill hasn't been too helpful here. I've posted a picture of the coin and any info I have about it.
Thanks for reading and I hope you have a great day.
